Proof of Forever

From debut author and poet Lexa Hillyer comes the lyrical story of four seventeen-year-old friends who receive an unlikely chance to relive the perfect summer . . . and the devastating secret that could unravel it all. Elegant and evocative, Proof of Forever is one of those first novels that hooks you from the beginning and builds toward a stunning-and unexpected-end, calling to mind Gayle Forman and Ann Brashares.
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.
