Proof of Forever, by Lexa HillyerRead about the other entries on the list.
Hillyer’s debut has been called “The Sisterhood of the (Time) Traveling Pants for a new generation,” because instead of a magical pair of formfitting jeans, you’ve got a photo booth that transports four former best friends back to a summer camp session two years prior. Joy, Tali, Luce, and Zoe must mine the past two years to discover where they went wrong, and what made Joy walk away from their friendships with no explanation. As they retrace their steps during the week they spent at Camp Okahatchee, taking care not to change the past, they stumble upon the dark secret that divided them.
