Hidden Deep by Amy Patrick

Sixteen-year-old Ryann Carroll has just run into the guy who saved her life ten years ago. You might think she’d be happy to see him again. Not exactly. She’s a bit underdressed (as in skinny-dipping) and he’s not supposed to exist.

Publisher Description

He isn’t supposed to even talk to a human, much less fall in love with one…

After her father’s affair, all Ryann wants is to escape the family implosion fallout and find a little peace. She also wouldn’t mind a first date that didn’t suck, but she’s determined not to end up like her mom: vulnerable, betrayed, destroyed. Ryann’s just moved into her grandma’s house in rural Mississippi, the same place where ten years earlier she became lost in the woods overnight and nearly died.

She’s still irresistibly drawn to those woods. There she encounters the boy who kept her from freezing to death that long ago winter night and was nowhere to be seen when rescuers arrived. He’s still mysterious, but now all grown-up and gorgeous, too. And the more she’s with him, the greater the threat he poses to Ryann’s strict policy– never want someone more than he wants you.
