Touched by an Alien

2010

Marketing manager Katherine "Kitty" Katt had just finished a day on jury duty. When she stepped out of the Pueblo Caliente courthouse, all she was thinking about was the work she had to get caught up on. Then her attention was caught by a fight between a couple that looked like it was about to turn ugly. But ugly didn't even begin to cover it when the "man" suddenly transformed into a huge, winged monster right out of a grade Z science fiction movie and went on a deadly killing spree. In hindsight, Kitty realized she probably should have panicked and run screaming the way everyone around her was doing. Instead she sprinted into action to take down the alien. In the middle of all the screeching and the ensuing chaos, a hunk in an Armani suit suddenly appeared beside her, introduced himself as Jeff Martini with "the agency," and then insisted on leading her to a nearby limo to talk to his "boss." And that was how Kitty's new life among the aliens began...Touched by an Alien is the thrilling first installment of the Alien novels.

The discovery that Martini is actually a member of the Alpha Centaurion Royal Family brings additional bad news—emissaries are on their way to see if Kitty's royal bride material. And they're not the only things coming from the Alpha Centauri system. Amazonian assassins, spies, alien beasties, shape-shifters, and representatives from the Planetary Council, combined with a tabloid reporter who's a little too on the mark, create a deadly situation for Kitty and the rest of Alpha Team. When the assassins strike far too close to home for anyone's comfort, Kitty realizes it's going to come down to more than throwing a bouquet—she's going to have to face an entire planetary consciousness and dethrone a monarch in order to make it to the church on time...

Alien vs. Alien

2012

Jeff and Kitty Katt-Martini and the rest of the American Centaurion Diplomatic Corps are still recovering from their introduction to Washington D.C. politics, parties, and conspiracies. So when compromising pictures arrive, no one’s too surprised. They’re also the least of anyone’s worries. Evil androids running amok, birds of all kinds and from all places creating havoc, a Senator trapped in an ever-tightening web of intrigue, and escalating international tensions all seem tough but manageable. But the disappearance of Jeff Martini and Charles Reynolds during the International One World Festival signals more than the usual nastiness—and it looks like even ACE can’t help them. Then new trouble arrives in old packages and even with the best hackers in the world, beings from near and far, the full might of Earth’s military, and the Wonder Twins on their side, Centaurion Division’s outmanned and outgunned. Now Kitty’s racing against the clock to find not only Jeff and Chuckie, but to keep the peace between Middle Eastern countries, all while searching for the bases of super-soldier operations—to stop them or die trying.

Alien in the House

2013

Jeff and Kitty Katt-Martini have learned the ins and outs of Washington politics, not to mention how to prevail in intergalactic war and foil dangerous plots. But, in the aftermath of Operation Destruction, the Gower girls’ powers are burned out, the entire A-C population has been “outed” as the aliens living on Earth that they are, and, worst of all, ACE is nowhere to be found. Then murder and mayhem are served up at an important dinner party at the American Centaurion Embassy, and when the dust settles Alpha Team and the Diplomatic Corps have more problems than just a dead Congressman. Is there a single criminal mastermind—or multiple enemies—behind all the conspiracies that want Kitty dead and the A-Cs gone or co-opted to become the War Division? The return of the best assassins in the business, the reappearance of two individuals long-presumed dead, Agent Malcolm Buchanan felled by something no one can identify or cure, and new technology that can block even the most powerful empath on Earth … all of this means the game’s officially afoot. Then Vance Beaumont comes to Kitty with a wild theory that someone is systematically killing off the House of Representatives… It’s up to Kitty and the rest of the gang to find out what’s really going on and why. But will they be able to stop the killer or killers before the rest of the U.S. House of Representatives become casualties? And will the replacement Representative for New Mexico’s 2nd District, who happens to be Jeff Martini, be the next to die?

Alien Research

2013

When rumors of a new super-drug surface, the FBI comes to Jeff and Kitty Katt-Martini for help. It becomes quickly apparent that the drug is merely the tip of a deadly iceberg and a much more insidious plan is underway involving Titan Security, Gaultier Enterprises, and YatesCorp. As newly discovered A-Cs and hybrids begin to surface, each with expanded and deadly talents, more and more signs point to a new evil genius who’s using the A-Cs and their enemies both as guinea pigs. Then Area 51 and the Dulce Science Center go silent while Alpha Team, Airborne, and most of the worldwide A-C Security team are there for training. And if that’s not bad enough, Centaurion Division is hit with more bad, and deadly, news: Chernobog the Ultimate, isn’t a hacker myth, he’s a real person—and he’s on the bad guys’ side. Now Kitty and company must find the real Dr. Feelgood and stop him or her before the latest version of Surcenthumain hits the streets and more people they love are harmed, or worse. But when the inconceivable happens, Kitty’s focused on two things only: reviving the ACE entity before their enemies realize Earth’s best protection isn’t actually active…and revenge.

Now Alpha Team and the Diplomatic Corps have to make sure that no one spots that there’s been a switch, while keeping World War III from happening.

Alien in Chief

2015

The Mastermind has upped his game . . . As Kitty can tell you, it's not easy being the wife of the vice president - especially not when he's an alien from the Alpha Centauri system. And being a parent of preternaturally talented children, don't even go there. But she and her A-C husband, Jeff, have learned how to roll with whatever life and the bad guys throw at them - they think. Kitty & Company have been savouring a few months of quiet since they got back from Beta Eight.

When the Alpha Centauri Planetary Council requests a visit with the president and vice president, things look politically dicey.

Camp Alien

2016

The President and First Lady, aka Jeff and Kitty Katt-Martini, don't get any downtime once the Mastermind has been revealed to the world. Not only do they have myriad high-level government positions to fill, but the scrutiny and pressure on this Administration has gone into overdrive. The sudden reappearance of a long-forgotten adversary turns out to be the tip of the iceberg. New robots and androids attacking, old enemies making new alliances, and new aliens with interesting abilities almost overshadow the fact that the U.S. still has to host a peace summit at Camp David between Israel and Iraq. It's clear that while the Mastermind may be down, there are plenty of others ready to take his place - and all that stands between them and success are Kitty and Company. Kidnappings, rescues, creepy hideouts, a hidden black site, and a domestic dispute that could end Jeff and Kitty's marriage are nothing compared to find not one but two hidden labs where dangerous and deadly things are brewing. But when the President and his entourage finally get to the peace talks, things are no better. Mossad rightly suspects something's wrong with both their Prime Minister and the President of Iraq. A hidden in-control superbeing, an android replacement, and an army of Fem-Bots turn the peace talks into a Battle Royale that the team might not actually survive. And if they don't make it, Earth won't make it, either. But no pressure.

Alien Nation

2016

It’s a typical day of bureaucracy and stress for President and First Lady Jeff and Kitty Katt-Martini, made more stressful when alien spacecraft are spotted making a beeline for Earth, none of them from the Alpha Centauri system. Then a cryptic request from an old adversary pulls Kitty out of the White House and into an explosion—and an even more explosive situation. Not only is the Mastermind back in the game, influencing the Club 51 True Believers to find and destroy all Centaurion bases, but he’s also found a dangerous benefactor and created some frightening new cloning abilities. And, just to make things a little more challenging, those alien spacecraft are coming to ask Kitty for protection, and asylum on Earth. Police stations being blown up and war helicopters in play aren’t enough to keep Kitty down, especially when she’s got some new alien friends helping out. But what these aliens share will rock the world—the other aliens on their way to Earth are fleeing an enemy so terrifying that even a Z’porrah ship is trying to get to Earth for safety and protection. And if Earth isn’t able to stop this threat, there may not be anything left of humanity. Now Kitty and Company have to figure out where the Mastermind is and stop him, before any new aliens land. And then they have to save the world from a deadly invasion. Or, as Kitty calls it, Thursday.

Aliens Abroad

2018

With the human population growing and alien refugees pouring in from around the galaxy, Earth is becoming too overcrowded to sustain itself—and the solar system is filling up with the alien overflow. Advanced technology from the Alpha Centauri and Vatusan systems offers one possible solution. It's time to explore new planets and see if any uninhabited ones can be claimed. The President and First Lady, aka Jeff and Kitty Katt-Martini, aren't supposed to be on this mission, but what looks like a snafu during a political photo op on the newly christened Distant Voyager spaceship turns out to be a call for help from a planet that might be Earth's salvation...or its destruction. The discovery of a world at the opposite end of the galaxy that seems like it could be a twin to Earth creates the usual issues for Kitty & Company. It also raises questions of Z'porrah and Ancient influence—not to mention cloning, the multiverse, and, scariest of all, whether or not the Black Hole Universe Police are starting to take too much of an interest in this particular universe.

Aliens Like Us

2022

AUTHOR NEWSLETTER 13 Feb 2019 No date set for Aliens Like Us as of yet. Gini stated that she is having to rewrite it. Author, 1-28-2019: Since the last quarter of 2016 life has just been pounding at my family and moving across the country was only part of that. I've been buckling under the pressure. Plus, Aliens Like Us wasn't done and needed a lot of work to be the book in my head that I've described to my editor. We made the hard choice to pull it off the schedule so that I could do a reset and feel the joy, versus the pressure, of writing. Aliens Like Us WILL be done and back on the schedule once I finish it, but I needed to admit that I couldn't keep up the pace after the last couple of years. So, Kitty will be coming back, just a little slower than originally planned. Katherine "Kitty" Katt faces off against aliens, conspiracies, and deadly secrets in the seventeenth novel in the Alien series, where sci-fi action meets steamy paranormal romance. When a call for help from an unknown entity comes to Kitty, she figures it's just business as usual for her life. Only the call isn't from someone in her own universe but from one of the many others, where her life is even more different than the one she discovered in Bizarro World. And, this time, it's not just Kitty who changes universes. The fate of the multiverse is now resting on Kitty and company's shoulders, but they may not be able to save it alone—and the help Kitty's come to rely on may not be able to intervene, assist, or even show up to watch. Or, as the multiverse calls it: Game On.
