"Profiler Sarah Armstrong knows what it's like to be in a sticky situation. As a single mother and one of the few female Rangers in Texas history, she has had to work twice as hard to rank among the best cops in the Lone Star State. But when megawealthy businessman Edward Lucas III is found murdered along with his mistress, their bodies posed in grotesque ways, Sara quickly senses that this will be the deadliest case of her career. While others focus the investigation on Lucas's estranged wife, Sarah disagrees and hunts a suspect only she believes in. Yet nothing in her career could have prepared her for the horror of a young man who believes he has been sent from heaven to massacre innocent people. When Sarah picks up on the killer's elusive trail, following his scent all over Texas, the psychopath makes her his next target. And as Sarah closes in, the madman sets his sights on all she holds dear. Singularity features a feisty, funny, and tough heroine and a truly creepy killer, as it races along to a chilling and unexpected climax."--Publisher's description.
