The witch moon is almost upon them. Mikael and Melody have been waiting for what has felt like a life time for its arrival. The two mates find themselves snooping around the Tarfala Research Station. They find themselves inside the Isfallglaciaren, a glacier that holds the secret to Mikael's past. Melody is there by his side all the way. Of course, Olga is not far behind. She has her own plans for Mikael and will not let a Sami witch get in her way. It's a race to the full moon. Who will be the first to howl to its power?
