After twenty-one years of no leads on the man who killed Grams and now Pops, the killer, Tobias slips up and reveals his true identity to Sadie. Between training for their elemental powers, new powers surfacing almost daily, Luca and Colin being stuck in the medical ward, and the killer on the loose, Sadie and Izzy are under a lot of stress. As the GWP seeks answers, they call in backup for plans they aren't sure will work.

Can the heroes overcome their obstacles, defeat Tobias, and keep the spell book safe?
