Yuuhi, Phoebe, Cal, and Aaron have been stranded in the Siberian tundra as part of their Ritual Ordeal, where they must survive for a month in order to come into their own as werewolves. But their ordeal has taken a life-and-death turn as they are relentlessly pursued by Gargantuas—vicious werewolf slaves bred for war. And just when things couldn’t be dire enough, a nasty blizzard hits, separating Phoebe from the rest of the pack!
