Beautiful Bastard — Christina Lauren

An ambitious intern. A perfectionist executive. And a whole lot of name calling.

Whip-smart, hardworking, and on her way to an MBA, Chloe Mills has only one problem: her boss, Bennett Ryan. He's exacting, blunt, inconsiderate--and completely irresistible. A Beautiful Bastard.

Bennett has returned to Chicago from France to take a vital role in his family's massive media business. He never expected that the assistant who'd been helping him from abroad was the gorgeous, innocently provocative--"completely infuriating"--creature he now has to see every day. Despite the rumors, he's never been one for a workplace hookup. But Chloe's so tempting he's willing to bend the rules--or outright smash them--if it means he can have her. All over the office

As their appetites for one another increase to a breaking point, Bennett and Chloe must decide exactly what they're willing to lose in order to win each other.
