Rewind Protocol

14-year-old Jax finds an old pager that allows him to "e;rewind"e; time by exactly 60 seconds, once per day. It seems like the ultimate social cheat code until he realizes that every time he rewinds, a "e;Shadow Double"e; of himself is created in a parallel timeline. These doubles are starting to slip into his world, trying to take over his life. Jax has to find the other "e;Protocol"e; users at his school to figure out how to merge the timelines before he is replaced entirely.
