Bett and Avery are sent, against their will, to the same camp for the summer vacation. Their dads hope that they will find common ground and become friends - and possibly, one day, even sisters.
Against all odds, the girls soon can't imagine a life without each other. But when the worst happens, and their dads break up, Avery and Bett must figure out a way to get them to fall in love again. Is keeping a family together as easy as they think it is?
From two extraordinary authors comes this moving, exuberant, laugh-out-loud novel about friendship and family, told entirely in emails and letters.
