The Duality Principle — Rebecca Grace Allen

Sometimes A + B = O. Yes. Oh, yes. Just like that.

Gabriella Evans's life exists in terms of logic and definitions. She's holed up in Portland, Maine, for the summer to work on her PhD thesis, but something is screwing up her concentration: the rumble of a motorcycle every time the embodiment of her rough-and-tumble fantasies rides down her street.

When her best friend talks her into a blind date, she finds herself out with the opposite of her fantasy. He's polite and well-mannered, yet something behind his crisply tailored shirt doesn't add up -- a rebellious gleam in his eye that piques her curiosity.

Orphaned at fifteen, Connor Starks has finally put the years of failing grades, breaking laws and breaking hearts behind him. The only holdover? His penchant for getting down and dirty in public places. But Gabriella makes him want to prove he's become a better man.

Nothing intrigues Gabriella more than a problem she can't solve. But the more Connor tries to bury his past, the more determined she is to uncover it. And what she finds makes all her trusty logic begin to fail her…

Warning: This book contains a summer romance, dirty talk, dockside kissing, motorcycles and tattoos. Features a rebellious nerdy girl with an appetite for outdoor sex and light spanking, and a bad boy who's turned good…or at least he's trying.
