Here is the synopsis from GoodReads if you are interested:
Dancing with someone is an act of trust. Elegant and intimate; you're close enough to kiss, close enough to feel your partner's heartbeat. But for Vanessa, dance is deadly – and she must be very careful who she trusts . . .
Vanessa Adler attends an elite ballet school – the same one her older sister, Margaret, attended before she disappeared. Vanessa feels she can never live up to her sister's shining reputation. But Vanessa, with her glorious red hair and fair skin, has a kind of power when she dances – she loses herself in the music, breathes different air, and the world around her turns to flames . . .
Soon she attracts the attention of three men: gorgeous Zep, mysterious Justin, and the great, enigmatic choreographer Josef Zhalkovsky. When Josef asks Vanessa to dance the lead in the Firebird, she has little idea of the danger that lies ahead – and the burning forces about to be unleashed.
