When a simple mistake thrusts Knox into Charlie's bookstore, he finds himself smitten with the young unicorn. Two lives couldn't be more different on the outside, but Knox has a secret, one he's never shared with anyone other than his family. One that proves he's not so different from Charlie after all. Unable to ignore the chemistry between them, Charlie and Knox grow closer, but as they do, trouble descends on the small paranormal community, threatening to keep them apart. The two must come together, trusting in what they feel so they can overcome the threats to their union. When secrets are revealed and truths admitted, bonds form that won't ever be broken. Still, when it comes to tigers and unicorns, it might not be enough to save them.
