Love stories aren't supposed to be written in blood. Theirs wouldn't work any other way. Deacon Thorne has perfected the art of hunting alone. Silent, deadly, and colder than a morgue in January, he spends his time taking down men who prey on children. He watches, confirms, and strikes when they least expect it, delivering justice with a nostalgic touch. So when a pint-sized hurricane crashes his kill scene with a wink and a smile, he realizes he's met a new kind of nightmare. Scout Prescott is five feet two inches of curves, charm and sass, a siren with a sweet tooth and an alarming caffeine addiction. But beneath the sparkle beats the heart of the notorious Stitcher, a serial killer who turns monsters into macabre art, one perfectly placed needle at a time. When she's tasked to find Deacon and recruit him into the Hollow, a secret society of killers who hunt their own, the mission seems simple. Team up, make the kill, and move on. But soon the world around them begins to shift, and an unknown threat closes in, leaving broken bodies and shards of glass in its wake. Scout and Deacon are forced to drop their defenses and work together to find out who's pulling the strings. But the most dangerous thing they uncover might just be each other.
