Killman Creek by Rachel Caine

A #1 Wall Street Journal bestseller.
Every time Gwen closed her eyes, she saw him in her nightmares. Now her eyes are open, and he’s not going away.
Gwen Proctor won the battle to save her kids from her ex-husband, serial killer Melvin Royal, and his league of psychotic accomplices. But the war isn’t over. Not since Melvin broke out of prison. Not since she received a chilling text…
You’re not safe anywhere now.
Her refuge at Stillhouse Lake has become a trap. Gwen leaves her children in the protective custody of a fortified, well-armed neighbor. Now, with the help of Sam Cade, brother of one of Melvin’s victims, Gwen is going hunting. She’s learned how from one of the sickest killers alive.
But what she’s up against is beyond anything she feared—a sophisticated and savage mind game calculated to destroy her. As trust beyond her small circle of friends begins to vanish, Gwen has only fury and vengeance to believe in as she closes in on her prey. And sure as the night, one of them will die.
