Magicstorm (Heart of a Vampire, Book 4)

When a mortal cop must delve into the paranormal, only a Viking vampire can save her soul, and her heart.

Detective Celeste Wilder knows who she is, a damn fine cop. But when the recently dubbed ‘Cult Murders’ start back up, this time targeting city prostitutes she’s sworn to protect, she’s thrown into a world of paranormal creatures she never believed existed. And now, they’re out to keep her from uncovering even more secrets.

An immortal Viking vampire, Brandon Wulfgar knows something is strange the moment he sees Celeste valiantly fighting for her life against a group of rogue vampires. When he’s asked to work with her--solve the crime while keeping the mortal woman safe--he figures no problem.

But as the undeniable connection between them grows and danger appears from every side, they will have to trust one another not just for their lives, but for their very souls.
