Books in the The Quantico Files series

When authorities contact the FBI about bodies found on freight trains--all killed the same way--Alex Donovan is forced to confront her troubled past when she recognizes the graffiti messages the killer is leaving behind. In a race against time, Alex must decide how far she will go--and what she is willing to risk--to put a stop to the Train Man.

When dark-haired women across Virginia begin to suddenly disappear, FBI behavioral analyst Alex Donovan is tasked with hunting the kidnapper down. But when Alex herself is baited and abducted at an abandoned amusement park, her partner Logan Hart and the BAU team fear Alex might not make it out alive this time.
