On the first day of sixth grade, Felix Woolfe turned into a cat.

As it turns out, becoming a werecat is just the first sign of trouble ahead.

Miss Gray, Felix's mentor and fellow werecat, tries to warn him about werewolves, witches, and Were hunters, a dangerous type of witch who hunts Weres like them.

When a strange family moves across the street, Felix is suspicious of their son, a sixth-grade student like him.

Then Miss Gray goes missing.

The timing convinces Felix that the new family is filled with dangerous Were hunters and that they have Miss Gray trapped in their home.

Felix must find Miss Gray and discover how to stop the would-be hunters. He's willing to do whatever it takes, even if that means using forbidden magic.

Will Felix be able to channel his powers and destroy the threat of hunters? Or will using new magic only be the beginning of a long game of cat and mouse?
