The retake

"Zoe has lost her best friend. She and Laura used to do everything together -- take silly selfies, join the same clubs, even throw surprise birthday parties for each other. But lately things have been weird. Laura's posting photos of herself hanging out with other girls. She isn't returning Zoe's texts. She doesn't even sit with Zoe at lunch anymore, Zoe is heartbroken -- all she wants is for things to go back to normal. Then a magical app downloads on her phone ... and thing get even weirder. Suddenly Zoe can travel back in time to the exact moments when their friendship began to fall apart. It's a dream come true -- Zoe can fix things, and she and Laura can be friends again!"--Jacket flap.
