Before Dawn (The Hunters, #1)

Mercy Jansen's dreams are filled with erotic interludes with a man whose face she never sees — and she always awakens before the scraping of sharp teeth along her skin turns into something more dangerous.

While uneasy about her subconscious mind, Mercy goes on with her daily life, which includes organizing a costumed fundraiser at the museum where she works. The event attracts more people than she'd expected, including a man who makes her knees go weak — and proceeds to turn her preconceived notions of reality upside-down and inside-out by pulling her into a shadowy, violent world where her erotic dreams threaten to become an all-too-real nightmare.
