Dying artist Ramona Escobar is desperate to save enough money to care for her Alzheimer's-afflicted mother before she succumbs to anemia. When she innocently takes a job copying a painting and it turns out that the owner plans to sell it as an original, Ramona turns to a friend, gallery owner Diego Rivera, a vampire who's been alive for hundreds of years, although she doesn't know it. Together they battle the bad guy and Ramona's disease. In Blood Calls (3), Caridad Pineiro's characters that work well together. Her story is fast-paced and the dialogue is good, but the book could use more vivid description. Several times Diego goes "vampire," but readers don't get a solid vision of what it looks like.
