Whether he's hunting sadistic serial killers or protecting what's left of his shattered makeshift family, Detective Petrosky's wise-cracking snark and intolerance for even the tiniest smidge of nonsense makes him the most endearing jerk to ever wear a badge. With heart-pounding twists, multidimensional characters, and enough fearless intensity to leave you breathless for more, the Ash Park series by clinical therapist turned bestselling author Meghan O'Flynn has everything you could want. If you liked Gillian Flynn's , Chelsea Cain's , or Jo Nesbo's series, you'll love Ash Park. Ash Park, a run-down suburb of Detroit, might not be the most idyllic place to live, but for Hannah Montgomery, it's safe. At least, it feels that way until a serial killer starts dicing up women from the shelter where she volunteers. Hannah manages to convince herself the killings have nothing to do with her brutal past—but then her boyfriend is murdered in the same ruthless manner as the others. And the police think she may have had something to do with it. The cops are right about one thing: Hannah is responsible. Because she knows who the killer is. Now she must face the fact that she brought a monster with her to Ash Park—and his appetite for blood is insatiable. Shannon Taylor takes no prisoners—save the ones she tosses into lockup. Between convicting criminals as an Ash Park district attorney, dealing with her jerk ex-husband (who also happens to be her boss), and caring for her dying brother, Shannon is already stretched thin. So she's less than thrilled when new evidence from a closed case emerges—evidence suggesting she threw a young mother in jail for a murder she didn't commit. Shannon knows the girl is hiding something. But something, or someone, has frightened her into silence. When Shannon becomes the target of a series of cryptic and bloody warnings, she begins to understand the girl's fear. But if she wants to keep her family safe, she has no choice but to expose the true killer. Will her persistence free an innocent woman, or will it turn her family into helpless targets in a madman's game? Conviction runs deep. Courage runs deeper. And nothing in Ash Park is as it seems. Newly-married detective Curtis Morrison spends his days working to heal the ails of society to make up for his own checkered past. But though he's come a long way from a life of deadly secrets he can't fully recall, not even his wife and baby daughter can silence the old addiction still rattling around in his brain. And he's about to learn that a history like his is not one you can escape from. When his wife and child go missing, Morrison finds himself drawn into a nightmare game controlled by a sadistic monster hell-bent on making him pay for sins he's repressed for nearly twenty years. But whoever took his wife isn't after her—they want Morrison to suffer. Now Morrison must reexamine a past he thought he'd left behind to save the people he loves, awakening a beast he's worked hard to forget. What he discovers is far worse than he imagined, every clue dragging him further from the life he's painstakingly built. The clock's ticking. And this time, he might not make it out alive.
