Dr. Melissa Donvers is the companion/physician to Ryder Latimer, her family's oldest friend and a vampire. Working with her ancestor's journals, she is continuing her father's search for a cure for Ryder's illness. She feels trapped by her duties, and her only break had been a night of passion with Sebastian Reyes, the brother of Ryder's lover. But Sebastian keeps away from emotional complications. When someone steals one of the journals, she asks for his help. Danger Calls (3) by Caridad Pineiro could be a lively paranormal, but it's slowed by internal dialogue and weighted down by backstory.
