Strung II: The Valley of Death - Per Jacobsen

Thirteen months after the events in the first book of the series, Randall Morgan and his family still live a life of uncertainty. A life in which they–like the other scattered groups of survivors–must be constantly on guard.

But can they trust that it's not just another clever trap set by their invisible enemy?

And can they trust each other?
