"There is an underground society right in front of the human public that is known to all, but acknowledged by next to none. It is the most ill-kept secret of our time, and all of humanity is complicit in the dismissal of its very existence. I am speaking, of course, about werewolves." - Ivan Cavender After years of fighting, mankind and werewolves have settled into an uneasy coexistence wherein werewolves hide amid humanity, copying human appearance and behavior so well that they blend in with the crowd. It's not a perfect solution. Men still kill werewolves when they can. When hunters go after a werewolf, that's when River Grayson steps in to try and rescue them. Part of an elite rescue organization, River and her family have been saving werewolves for generations. But their already dangerous lives get even more complicated when a book throws the curtains hiding werewolves wide open, and suddenly it's all-out war in the streets between man and wolf.
