Was Mia's child hood best friend gone? Yes. Did she think he died? Yes. Was he actually dead? No.

Life must go on. That's Cass's new motto. After the huge attack on San Francisco by ElectroNite, whom she bravely fought against alongside her allies Blaze Boy and Quicksilver, the events hit her hard. But life must go on. Now, Cass continues her fight against the electric villain with Quicksilver, and a very unlikely friend joins the group. Whilst she's not at school, stressing over calculus, or at the pool swimming, Cass must begin training with her newest ally for the biggest fight of their lives. Together, can they finally defeat ElectroNite, and restore San Francisco to peace?
