In the Forests of the Night (Den of Shadows Series)

By day, Risika sleeps in a shaded room in Concord, Massachusetts. By night, she hunts the streets of New York City. She is used to being alone. But someone is following Risika. He has left her a black rose, the same sort of rose that sealed her fate 300 years ago. Three hundred years ago she was human. Now she is a vampire, a powerful one, and her past has come back to torment her.
