Apex of the Curve by A.J. Downey

Fenris had always considered himself a lone wolf among the pack when it came to the club life. Though now that his best friend had found an ol’ lady of his own, he had started entertaining the idea for himself. He never took stock in the old adage ‘be careful what you wish for’ but then Aspen was suddenly standing in front of him with those big, hard-to-resist green eyes and he was smitten.
Aspen’s life had been turned upside down and inside out through a series of unbelievable and unfortunate events – and the hits just kept on coming. She wasn’t sure if her luck was turning or getting worse when she woke up in the badass biker’s bed, but Fenris knew…

She was just at the apex of the curve in the road her life had taken.
