Ellie and Charlotte's friendship has a set of rules they wrote long ago--and Ellie has just broken Rule #5. The morning after Charlotte's wedding, Ellie has woken up in bed with Logan, Charlotte's brother, who she's been secretly admiring for ages.

With Charlotte away on her honeymoon, the pair, not satisfied by a one-night stand, agree to keep their fling going until Charlotte returns. And to assuage the guilt, they'll work together on renovating the newlyweds' bedroom as a welcome-home surprise.

But no matter how hard they try to stick to the plan, two weeks may not be nearly enough--and who knows what will happen when Charlotte's honeymoon is over . . .
