Lucy Carver is like Sherlock Holmes in ballet flats, but her photographic memory is more albatross than asset and something she usually keeps hidden. Noticing something's amiss at her dead-end job, she jumps at the chance to use her ability for good. That is, until, a man is murdered, and the killer targets her. Detective Eli Reyes is overbearing and pompous, way too hot for Lucy's own good. He seems as determined to ruin her relationship with her boyfriend, John, as he is finding the murderer. Eli brings Lucy in on the case, only to cut her loose when he realizes he's gotten more than he bargained for. When childhood memories invade her present, Lucy discovers a mystery bigger than she imagined. With the killer after her, and Eli nowhere to be found, she's determined to expose the truth no matter what—before trouble comes knocking...again.
