Proximity (Wanderlust Series Book 2)

Love sometimes hides in plain sight.
Savannah is one of the boys—fun loving, adventurous, a general contractor, and dive master extraordinaire. There isn't much she takes seriously about herself, or at least that's the impression she likes to give off. Women often misjudge her based on her looks so she's gravitated toward a group of men who accept her 'as is'—her SCUBA diving club.
Bill has known Savannah's wild side for years and has been comfortable playing the role of best friend. As part of the Dallas Divers, he's shared many adventures with the group from diving the Blue Hole in Belize to exploring the Great Barrier Reef in Australia. When the team heads out to Costa Rica for a series of cave dives, he knows something is off but can't quite justify his nerves.
Catastrophe happens shortly after their immersion in the cave. With the entrance blocked from an earthquake and separated from the rest of their team, Savannah and Bill are forced to find another way out while battling aftershocks, rising tides, and an undeniable attraction that they've ignored for too long.
