Alexandra "Alex" Donavan overcame her troubled upbringing and is now a member of the FBI's elite Behavioral Analysis Unit. When authorities in Kansas and Missouri contact them about bodies found on freight trains traveling across the country-- all killed in the same way-- she recognizes the graffiti messages the killer is leaving on the train cars. When the BAU sends her to gather information about the messages from her aunt in Wichita, Kansas, Alex must face how far she'll go-- and what she is willing to risk-- to put a stop to the Train Killer. -- adapted from back cover
