Gary Waldman is a grief-stricken former tennis coach slowly reentering the world after the death of his wife. As he struggles to remain a good father to his six-year-old son, Waldman finds unexpected comfort and stability in the rule-bound confines of the TSA, working as a Transportation Security Officer in upstate New York. But his life is turned upside down again after he uses CPR to bring a passenger back from the dead.

Part airport thriller, part family drama, part love story, In Security explores how those who strive to protect us are often unable to protect themselves. Can someone who does security work ever feel truly safe? As the novel races toward its conclusion, Waldman discovers the limits of what he can control, both at the checkpoint and under his own roof.
