Derek Hale is dead. It's Stiles' fault. He'll stop at nothing to kill the creature who did it. The only problem is that his new work partner in National City looks like his dead soulmate.

Melissa and Scott McCall are hoping their move to National City from Beacon Hills is exactly what they need for a fresh start, but when a meteor crashes down right in front of them, they are left with life-altering abilities and powers. Helping the McCalls get a grasp on their newfound abilities is resident hero, Supergirl, and her friends at the DEO.
