I'm looking for a particular werewolf/romance story. One with the main character girl's school being invaded by her mates pack. He's the alpha and hates her in the beginning and cruel. His beta is her long lost brother. She finds out she was her old pack's dead alphas daughter, if I remember correctly. He ends up slowly falling for her. And ends up getting married towards the end of the book, about the same time she has a kid with him.
I don't know why it's not in my library, but it is supposed to be. Any help would be awesome and amazing. Thanks a bunch for the help!
