After a smooth jump to Dimension 9, Chase, Alyx, and chimera pup, Bo, discover that this world's peaceful existence only extends as far as the local high school. A different kind of battle wages there, and the identity of the school bully is a surprise they never anticipated.
When Chase decides they have no choice but to enroll at Dune Harbor High and repeat their senior year, Alyx is less than thrilled.
But the two soon discover the influence just one person can have over the decisions, lives, and even deaths, of those around them. While they try to prevent one tragedy, another one unfolds even as Chase unravels one more piece of his family history. What he discovers will leave him reeling, and his life will never be the same.
