Waterfall Effect — K.K. Allen

From RT Book Reviews New Adult Award Winner, comes a suspenseful small town mountain romance. Lost in the shadows of a tragedy that stripped Aurora of everything she once loved, she's back in the small town of Balsam Grove, ready to face all she's kept locked away for seven years. Or so she thinks. As one of the victims of a string of mysterious disappearances in the small, picturesque Appalachian Mountain town, darkness has become her home -- her safe blanket when the world reveals its true colors. But as the walls of darkness start to move in on her, she knows the only way to free herself from her past is to face it, head-on. She just needs to figure out how. Upon arrival, Aurora isn't expecting her first collision to be with the boy she left all those years ago. The boy who betrayed her trust with no regrets. The boy who is no longer a boy, but a man with the same stormy eyes that swept her into his current before she ever learned to swim. She'd thought he was safe. He'd thought their path was mapped out. Turns out neither of them was ready for the crash at the bottom of the cascade.
