Who let the wolves out?

Six months have passed and summer vacation has finally ended. It's time for Micka and Noah to return to Bran Prep High for their last year of high school. After investigating for the FBI—which consisted of getting into sticky situations with the supernatural and constantly risking their lives to save their friends and, in fact, the entire world—Micka and Noah believe that they will finally be able to have a normal teenage life. But the FBI sends them on another investigation. This time, on werewolves. It doesn't help that Diego Dirus makes an unexpected visit, knocking on Micka's room and greeting his 'favorite pup' with a sexy grin, heart-melting accent, and bold sleeve tattoos. The boys quickly find themselves knee-deep in werewolf affairs. Maybe their senior year won't be as normal as they had hoped.

Who let the wolves out, anyway?
