Jump Boys

The jump across the multiverses was supposed to be easy. But when a miscalculation sends thirteen-year-old twins Jayce and Val Jump into another dimension, their reality splinters. They discover a girl who holds the key to time itself and the boys make a promise to her dying father to protect her and the secret. But mechanical malfunctions plague their small ship, terrifying space pirates chase them across time and space, and betrayal waits for them at home. If they ever make it home.
