Sizzling chemistry and tender friendship develops between two childhood rivals in this hilarious rom-com from the author of As Seen on TV.

Jude Stark is the bane of Molly Blum's existence. The former neighbors and complete opposites began a rivalry in grade school that continued all the way through high school, consisting of fights, pranks, and generally one‑upping each other—until one over-the-top prank changed everything. A decade later, their siblings have forced them to collaborate on a surprise co‑wedding anniversary celebration for their parents, and soon Molly and Jude are reverting to their old tricks.

But eventually, a reluctant friendship develops…along with an unexpected spark of sexual tension. The two come to discover they have more in common than they thought, including continually dating doppelgängers of each other, raising the question why are they seeking in romantic partners what they claim to hate about each other. They finally give in to their growing feelings, but will that old competitive spirit take over, or will they finally realize being on the same team is a lot more fun?
