Lord Alaric Valerian has a problem. His mother is visiting his castle for the first time, but she doesn't know that Alaric has filled every room with centuries of his artistic projects.

Desperate, he hires professional organiser Winnie Preston to help him tame the mess. Yet Alaric isn't prepared for bubbly, passionate Winnie to show up at his castle - she sets his fangs on edge, but the more he works with her, the more he wishes she could be his.

To complicate things further, Alaric's mother arrives with a surprise in tow: a bride. Shocked and dismayed, Alaric convinces Winnie to pretend to be his fiancée to avoid the dreaded union. What could go wrong? For one thing, Winnie still doesn't know Alaric's a vampire, and for another, Winnie's meddling book club suspects Alaric of a mysterious murder in the village.

Will their maybe-not-so-fake relationship survive once Winnie discovers the monster that lurks beneath his fangs?
