Defiant (The Blaze Trilogy) (Volume 1)

Sometimes love burns. The intelligent loner, Anson, soon learns this when he falls in love...but the girl he wants isn't what she seems. Poppy is part of a secret organisation of vampires trained to fight werewolves. She's been sent to recruit Anson, and if she fails, they'll both have to outrun the rulers of her society...or face death together.
