Talk about a blast from the past. They'd attended high school together and he remembers her as the quiet, adorably awkward and somewhat nerdy photographer he'd had a crush on, but because their lives were so different, he didn't dare cross the line with her, except for one drunken kiss. But now they're older, she's blossomed into a real beauty and he intends on crossing any line he can to protect her... and have her as his own.A woman who adamantly guards her heart encounters the one man who may be able to break down her barriers. When the past collides with the present, boundaries will be pushed and unbreakable hearts will be tested to the limit.
