Diego and Finn's peaceful life in Montana shatters when Diego unwittingly rips a hole in the Veil to the Otherworld - mysterious prophecies, dying fae, hostile government agents, and there's so much more that could still go wrong. After defeating an evil wendigo, a man and his pooka lover deserve a little quiet. Unfortunately, Diego and Finn's hard-won peace is disturbed when Diego, in a jealous rage, unwittingly rips a hole in the impenetrable Veil to the Otherworld. Separated, stuck on the other side of the Veil where Finn has to face old conflicts and Diego is the only human in a land of fae, the two of them navigate rocky waters between huge egos and ancient feuds. Worse still, some of the fae are dying of a mysterious illness and everyone believes Diego is the key to a cure. Things can't possibly get any worse, can they? Oh, yes - they can when the US government gets involved.
