Jessica Cooper and her SAR dog Luke are called out to a building collapse. What Luke discovers under the rubble shocks her. Then investigators discover that the explosion was intentional and link it to a series of other bombings. Jess’s husband Scott joins an FBI/ATF task force searching for the suspect. While Scott chases the bomber, Jess continues her SAR activities. On a dark night, during a violent persistent storm, Jess sustains a horrible loss and is plunged into a pit of despair, her faith shredded.

But God isn’t finished with Jess. As she slowly begins to cope, life takes a surprising, positive turn. Reenergized, she puts on her PI hat and stumbles onto a key to the bomber’s identity. Soon the mad chase to find him leads her into another storm on another dark night-and another test of faith.
