When the Stars Align: The Story of how two Worlds Collided

What would you do if you met an alternate version of you? When two worlds collide. Christopher and Eliza Myars's worlds are turned upside down as somehow, their universes interlocked upon witnessing a stellar collision on the day of their middle school entrance ceremony...but the downfall is that at random times throughout the day/week, agonising electric shocks would overtake their bodies and all of a sudden, the universes would swap, and they'd find themselves in the other's body.
