James, Hannah, and Wolf face their greatest challenge yet in the pulse-pounding conclusion to The Rift trilogy. “Just when you thought the story couldn’t get more riveting, Richards and Calvert dazzle, saving their best for last.” Finally reunited on an advanced, alternate Earth where the mighty Roman Empire never died, James, Hannah, and Wolf now stand at the precipice of an interdimensional war threatening to obliterate everything they’ve fought to protect. As the fabric of existence continues to unravel, unleashing anomalous storms and creating rifts large enough for unstoppable warships to traverse, the trio must find a way to repel a superior force bent on conquest. Impossible, yes, but also just the beginning of their problems. Because they’re in a battle for their very lives. And if the tears in the fabric of reality aren’t completely mended, both worlds will ultimately fall, regardless of which side is victorious. The explosive conclusion to The Rift trilogy delivers a relentless thrill ride packed with mind-bending twists and heart-pounding action, and a question that echoes through the can a trio of extraordinary individuals survive and defy all odds, or will two worlds be condemned to oblivion? “Richards is an extraordinary writer,” (Dean Koontz) who can “keep you turning the pages all night long,” (Douglas Preston) “Joshua T. Calvert has a gift for making nail-biting science fiction that you can’t put down. Get ready for some sleepless nights!” (M.A. Rothman, USA Today bestselling author)

Joshua T. Calvert has traveled the world—on foot, by Jeep, by bicycle, by motorcycle, and lots of other ways besides. As you might imagine, he's seen many things most people never see - including an Iranian prison cell, from the inside! In Kyrgyzstan, he fared slightly better, narrowly avoiding being kidnapped for ransom. Skydiver, scuba diver, martial artist, adventurer - his goal is to experience everything possible, and then make it real to you in his books. And he's made a good run of it so far: in the Philippines, he did police training on multiple types of firearms (despite being no fan of guns himself); dove in Asian waters among sharks and shipwrecks; and patrolled with Sumatran jungle rangers. That's what defines Calvert's approach to method writing: pushing himself beyond his own limits, to experience first-hand what his characters experience, to make your immersion in his stories as deep as it can be. For Ganymede Rises, after a slight detour with some smugglers in the deserts of Uzbekistan and the steppes of Mongolia, he traveled by dogsled and snowshoe to the Arctic Circle to experience first-hand what it's like to be utterly isolated in the coldest place on Earth. For his book The Fossil, he sat with professional pilots in flight simulators for Airbus A320 and Boeing 737 aircraft to learn what it's like to fly a passenger jet. His latest adventure: a parabolic flight with European Space Agency astronauts, to experience zero-gravity. All so he can describe it to you, in his own words.
