Killer Smile

2022

If looks can kill, a smile can be deadly. Special Agent Stella Knox became an FBI agent to find the dirty cops responsible for her father’s murder and make them pay. But fresh out of Quantico, her first case has her seeking justice for a different victim—three of them, in fact. The bodies of three teenage boys have turned up in a sleepy town outside of Nashville, TN. There’re no fingerprints, no DNA, and very little to connect the murders, except for a smiley face drawn in blood near two of the bodies. But why only two? The case makes zero sense, and the questions outnumber the answers. Are the crimes related? Could it be the work of one calculating serial killer, or are they looking for three separate assailants? One thing Stella knows for sure: someone is threatening the teenagers of small-town Cherry Farms, and they aren’t finished. As she and the team race against the clock to stop the nightmare that has descended upon this rural community, Stella has one more question...who will be next?

Another young woman has gone missing, and the local sheriff is freaking out because that makes three disappearances in the last two weeks under his jurisdiction.

Killer Shot

2022

After Special Agent Stella Knox’s friend and FBI tech ace Mac drops a bombshell regarding the death of Stella’s father, she can’t wait to follow up on the lead. But that’s put on the backburner when six people are abducted from a dinner party—the door open, the table laid, and the meal started. Even more disturbing is that a two-year-old is among the missing. With no sign of a struggle and the only fingerprints belonging to the guests, there’s little to go on. Soon, a body is found in a drainage ditch on the edge of town, shot in the back at close range. Followed by another. While Stella and her team scramble to piece together a limited set of clues, a madman is calling the shots in a sadistic game where even the winners lose it all. Now, it’s a race to find the remaining hostages...while they’re still alive. Twisted and spine-chilling, Killer Shot is the third book in the new Stella Knox Series by bestselling author Mary Stone and Stacy O’Hare that will make you wonder how far you’d go to save your life.

Killer Fame

2023

The cost of fame is paid in blood... It’s been an eventful twenty-four hours for FBI Special Agent Stella Knox. She’s saved her colleague from a murderer, rescued the same murderer, and watched the man who killed her father plummet to his death. Now, she’s not only tormented with questions about her father's murder, but new worries about her colleague and friend, Special Agent Hagen Yates, are plaguing her too. What should she do? A new case is a welcome distraction, so when two bodies are found, Stella dives into the investigation. The deaths are seemingly unrelated—one an apparent suicide, and the other a victim of robbery—except for a woman’s embroidered handkerchief found in victims’ pockets. It could be nothing. Or it could be a serial killer’s calling card. The truth is something far worse. And little does Stella know she’s playing right into the hands of a killer who’ll do anything for fame. Intense and chilling, Killer Fame, the ninth book in the Stella Knox Series by bestselling author Mary Stone and Stacy O’Hare, will leave you questioning the true cost of fame...and those inside the spotlight’s embrace.

A private jet explodes over Nashville, its sole passenger skewered on a skyscraper’s antennae during his descent. Why would a perfectly good plane fall out of the sky? The team quickly rules out pilot error and learn that the plane was meticulously maintained. This leads Stella and the rest of the team to a chilling conclusion: intentional sabotage. But why? A terrorist would have picked a more crowded plane. So who would want the pilot or the single passenger dead? When a second explosion occurs in as many days, the case grows more convoluted. They have one downed plane and now a car explosion. With a myriad of unconnected pieces, Stella wonders if they’re even part of the same puzzle. However, the closer Stella gets to finding the culprit, the more explosive the situation becomes...literally.
