The adventure continues when Abby and Derick begin their second semester at Cragbridge Hall, the most prestigious secondary school in the world. The year is 2074, and Abby and Derick are busy designing their own virtual worlds and learning to control new robot animal avatars, but when their Grandpa Cragbridge admits them into the Council of the Keys—a secret group of people who have keys to travel back in time—strange things begin to happen. One by one, members of the council are found unconscious and unable to wake, their keys stolen. Now Abby, Derick, mand their friends must scramble to figure out who is behind the attacks before they become the next victims, which would give their enemy the power to change the past—and forever alter the present and future. A page-turning, time-travel adventure that teaches powerful lessons about choice and consequence, believing you can do hard things, and valuing history. Unabridged audio book
