When White House tour director Selena Barrow is attacked in her office, the Capitol K–9 Unit goes on high alert. Selena's cousin is a person of interest in a congressman's shooting, and Selena has been collecting evidence to exonerate her. Could this be the break they're looking for?

Officer Nicholas Cole and his dog, Max, step in to safeguard Selena–and to keep an eye on the evidence. As the attacks escalate, Selena finds it increasingly difficult to keep her distance from her handsome protector. But with an unknown enemy watching Selena's every move, Nicholas will become her confidant...and her lifeline.
