Kaely Quinn's talents as an FBI behavior analyst are impossible to ignore, no matter how unorthodox her methods.

But when a reporter outs her as the daughter of an infamous serial killer, she's demoted to field agent and transferred to St. Louis.

When the same reporter who ruined her career claims to have received an anonymous poem predicting a string of murders, ending with Kaely's, the reporter's ulterior motives bring his claim into question.

But when a body is found that fits the poem's predictions, the threat is undeniable, and the FBI sends Special Agent Noah Hunter to St. Louis.

Initially resentful of the assignment, Noah is surprised at how quickly his respect for Kaely grows, despite her oddities.

But with a brazen serial killer who breaks all the normal patterns on the loose, Noah and Kaely are tested to their limits to catch the murderer before anyone else--including Kaely herself--is killed.
