Alpha One, leader of the wilderwolves, leads the Night Patrol straight into a werewolf-hunter trap. Freddy is expelled from Howlington after the council blames him - and his friendship with Scarlet - for the disaster.
When the wilderwolf hunting Freddy is exposed as Cherry, and sentenced to be defanged for her crimes, Freddy tries to prove that she can be reformed. Scarlet meets two other young wolfhunters who take a different approach.
Freddy Lupin manages to convince the pack elders to let him sit Howlington Academy's entrance test. Freddy must use all his poodle wits (and his best friend Batty's help) to win a place at the historically wolf-only academy.
It's Howloween, and Howlington is on lockdown. But when the students stage a play that goes wrong and the lockdown is disrupted, it will be up to the kids to save the grown ups from themselves - including Principal Pincus.
