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. 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.
