Could your closest friend be a killer?

When a body washes up outside Deception Cove, Washington, Jess Winslow-once a US Marine, now a trainee sheriff's deputy-is assigned to investigate. But when she realizes it's "Bad" Brock Boyd, a hometown celebrity lately fallen from grace, things become complicated. The last person seen with Boyd was her own boyfriend, Mason Burke.

An ex-convict and newcomer in town, Mason is one of the only people who can understand Jess's haunting memories of her time in Afghanistan-and her love for Lucy, her devoted service dog. Finding one another in Deception Cove has been the best thing to happen to either of them in years. So Jess knows Mason could never be guilty of murder-doesn't she?

As the facts of the case point ever more squarely at Mason, Jess must face that everything she thinks she knows about him might be wrong. A thrilling sequel to Deception Cove, and a heart-pounding adventure all its own, Lone Jack Trail pushes Jess and Mason to a shocking confrontation and will test everything they've come to love and trust in Deception Cove.
