Took me from my world

Molly Hanson has always been afraid of wolves. Ever since one had taken her brother, dragging his horror-stricken body into the woods to die, she tended to watch the forests instead of explore them. Instead of taking her brother back, her brother takes her, she becomes 'a wild one' against her will.
It's up to her to save her brother, and destroy the alpha male. Even if that means falling in love with him.
