    Summary

    He freezes, confused. Because that's Grace, he's sure, knows his heartbeat better than he knows Adrian's voice, but it also isn't.

    This human is small, his hair is different a little longer where Grace's has been cut. His glasses are different, a little wider, bigger on his face.

    And then the Short Grace is screaming, tripping over his own feet in his hurry to back away from Rocky, something crashes to the floor rolling away from Short Grace's hands.

    OR

    Rocky gets transported to Earth, where Grace is 14 years old, living with his older brother's Courtland and Colt. He needs to find a way back home, to his Grace, with only the help of a middle schooler. What could go wrong.
