Thomas and Viv Adler are the envy of their neighbors. One morning they wake up to find their porch pelted with eggs. It's a prank, Thomas insists; the work of a few out-of-control kids. But when a smoke bomb is tossed on their front lawn, and their car's tires are punctured, surveillance cameras show nothing but grainy images of shadowy figures in hoodies. Police dismiss the attacks, insisting it is the work of bored teenagers. As the assaults escalate into violence, each new violation brings with it a growing fear. Because everyone in the Adler family is keeping a secret-- not just from the outside world, but from each other. And secrets can be very dangerous. -- adapted from back cover.
