I just finished The Wheel of Darkness by Douglas Preston and Lincoln Child. 

I've read a few of the Preston/Child's books - Relic, Reliquary and The Cabinet of Curiosities.  They are all techno-thrillers to one degree or another, usually overlapping with serial killers and some kind of mysticism.

This one is no exception, as a dangerous object is stolen from a Tibetan monastery and the killer escapes on a new ocean liner, followed by FBI agent Pendergast.  Pendergast has moved from being an odd minor character, to being the focus of their novels, of which The Wheel of Darkness is on the tail end. 

Nothing unexpected here, but an OK read given that.
