<p>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,<em>Proof of Forever</em> 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.</p><p>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.</p><p>Wendy Wunder calls <em>Proof of Forever</em> &quot;<em>The Sisterhood of the (Time) Traveling Pants for a new generation!</em>&quot;</p>
