Abandoned by Cody McFadyen

The woman had been missing for almost eight years. Someone watched her, stalked her, kidnapped her, and held her captive in the dark all that time. No ransom demand, and no suspects. No answers, even now that the woman has been found -- thrown from an unmarked car in front of a beachside wedding -- alive but unbearably traumatised. All she can do is scream. Tracking a kidnapper who appears to have no motive, FBI Special Agent Smoky Barrett and her team are plunged into the most sinister and disturbing case of their careers. Then they start to find the others.

I read this in about 2 days and really quite enjoyed it. I know they think they have a helluva twist at the end, but I wasn't that blown-away by it. Still I'd recommend it as worth reading :) And I may have to consider looking for some other Cody McFadyen books ...
