Every year ten young she-wolves find themselves in the North Woods at midnight. All have one thing in common: they're forced from their lives because of someone. A mysterious man that the packs have named The Blade.
The Blade controls the five remaining North American packs, and he is not defied. The Blade is entrusted with protecting the packs from humans, as he conceals our borders and hides our presence. But everything has a price; his only request: that ten she-wolves go into the dangers of woods to battle their way back out. Every year ten go in, and no one comes out.
It is dangerous to play with knives.
