The lunar cycle was a funny thing. There were two full moons in January, none in February, followed by two in March, before it settled back into its usual monthly routine.

Snow fell heavily outside, and it was far too cold for her to sit with a transformed Remus and Draco, so with some clever wand work, Sirius had expanded the living room at the Den to accommodate two fully grown werewolves, Hermione, and himself.
