The world according to Sam Kirk has just turned upside down. His best friend and business partner, Delaney Michaels, has returned from vacation a new woman…a gorgeous, hot new woman. Suddenly Sam is thinking entirely inappropriate thoughts about his buddy. Worse, with Delaney's changed look, she's abandoning their friendship in pursuit of the picket-fence dream. It's a nightmare come true.

Then one night finds them tangling in the sheets.

It should feel wrong, wrong, wrong…instead, it feels very right. And now Sam knows exactly what he'd do to keep his best friend: absolutely anything.
