Ride the Tide by Julie Ann Walker

Once a fighter, always a fighter…

Former Navy SEAL Mason McCarthy is done being a fighting man. Now he and the Deep Six Salvage crew are working feverishly to find the wreck of the Santa Cristina and its legendary sunken treasure. Unfortunately for Mason’s peace of mind, chatty, brilliant historian Alexandra Merriweather has joined the hunt and there’s no avoiding her. Alex is exactly the kind of distraction Mason can’t afford right now…or maybe ever.

When a murderous enemy from Mason’s past threatens the Deep Six, he must rely on old instincts and the skills he honed from years of running black ops to make sure nothing touches Alexandra. But with their lives on the line and the adrenaline running high, it’s inevitable that sparks will fly.
