K-9 Confidential by Nichole Severn

This fierce K-9
Is facing killer odds
Security agent Granger Morais is stunned when he and his K-9, Zeus, confront the one person he thought was dead—and can’t afford to trust again. Helping ex-informant Charlie Acker discover who killed her young sister may be key to taking down her powerful extremist family. But when Granger must protect her from a ruthless cartel that wants her special skills, will his and Charlie’s troubled history—and reignited heat—keep them alive…or be the one trap they never saw coming?
