When a warlock from the magical world of the Morning Land murders Derek Ridder's friend, the LAPD detective gets a new partner. Her name's Tavia, and she's a brash, driven unicorn filly. She identifies the killer as Sir William Teach, the one man she's sworn to capture or kill at all cost.
Together, Derek and Tavia race to uncover Teach's dark plans to unleash an ancient evil in order to conquer both of their worlds. Their path takes them through Los Angeles and deep into the fantasy realm of the Morning Land.
Along the way, they discover what can break a mythical creature's heart, what can heal death itself, and whether or not one needs to be virgin-pure in order to touch a unicorn.
