Gregg Hurwitz, You're Next

Contractor Mike Wingate and his family are being targeted by a couple of very scary guys for reasons that Mike cannot fathom. Nor can we, although it seems to be related somehow to Mike's past, a sad childhood spent in a foster home waiting in vain for his father to come back for him.

The home hardened Mike, taught him some skills, and earned him just the sort of friend you need when people are gunning for you.

Hurwitz's stand-alone thriller is one of the most exciting books I've read in a while. The tension eased up briefly for me maybe 70% of the way through, when we started getting some answers about the mystery of Mike's past, but it picked up again. There's really nothing to complain about here. This was a great read.
