Joy, Tali, Luce, and Zoe were once best friends. Now they barely speak. That is, until the fateful flash of a photo-booth camera transports them back in time, to the summer they were fifteen—the summer everything changed. Photos fade. Friendships dissolve. Summers end. But this one will change the girls forever . . . again.
Wendy Wunder calls Proof of Forever "The Sisterhood of the (Time) Traveling Pants for a new generation!"
