Humans and wolves had found ways to coexist in peace for centuries, but that’s all it was. Coexisting.

But when Kyungsoo discovers that his mate seems to be an improbable link between humans and wolves, him and his pack, EXO, find themselves in the very epicenter of a species war 20 years in the making.
