Danger Calls (Mills & Boon Intrigue) (The Calling, Book 2)

One night was all it could ever be… Because Dr. Melissa Danvers was a vampire's keeper. Honor-bound to repay the man who'd always been there for her, Melissa hoped the 140-year-old immortal could uncover the mystery surrounding her parents' deaths. Complicating her mission was Sebastian Reyes, the young, sexy entrepreneur whose wild lovemaking left her sated, yet burning for more. One night of passion with the beautiful healer would haunt Sebastian the rest of his life. Now Melissa needed his computer expertise to unravel a crime and stay one step ahead of a desperate killer. Sebastian was strictly a no-strings-attached guy. Until danger and desire delivered him to the one woman his soul couldn't forget.
