In Taking, a serial killer, suspected to be using an RV camper, lures and kills women across the country—and the FBI turns to its youngest and most brilliant agent: 22 year old Riley Paige. Riley has managed to graduate the FBI academy, determined to make it as an FBI agent. But when she is assigned her first official case with her new partner—Jake—she wonders if she is cut out for the task. Riley and Jake, immersed in the RV subculture—and into the depths of the killer's mind—soon realize that nothing is what it seems. There is a psychopath at large, stumping them at every turn, and willing to stop at nothing until he has killed as many victims as he can find. With her own future on the line, Riley has no choice but to find out: is her brilliant mind any match for the killer's?

In Stalking, when two teenage girls turn up dead in different states, each strangled, and each killed within days of each other—the FBI calls in its brilliant new agent, 22 year old Riley Paige, to stop the serial killer before he strikes again. Riley, fresh out of the academy and off her last case, is settling into FBI life and to her new partnership with her mentor, Jake. She is starting to feel confident in her abilities—when this new case lands. It is a case that shocks her, that stumps her, and that rocks her self confidence to its very core. What do these two girls have in common? Why can't she figure it out? Is this killer as diabolical as she suspects? The only way to find out is for Riley to enter the dark canals of the killer's mind, to stare into the precipice of darkness—and to hope that it doesn't swallow her alive.
