In the Forests of the Night (Den of Shadows, #1)

By day, Risika sleeps in 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 three hundred years ago. Three hundred years ago Risika had a family- a brother and a father who loved her. Three hundred years ago she was human.
Now she is a vampire, a powerful one. But her past has come back to torment her.
