They've been there for each other through death and life, through pain and joy. Their love life has held them together through all external dangers. But what happens when the threat seems to come from within?

Charlie, half werewolf, has never felt so uncertain. Everything he's trusted in — his eyesight, his psychic ability, his confidence in making decisions — is under attack. Even his mate, his Life dancer, Luis, seems untrustworthy.

Luis, a psychic vampire, is consumed by terror and paranoia. Unable to tell fact from fiction, and feeling Charlie pulling away, he lashes out.

These two lovers who have stood the test of time find themselves on unsteady ground. Can their love prevail despite the terror working its way through the pack?
