This book is about a 14-15 year old freshman named Keira Millen. There are no demons, or dragons, or medieval battles or anything like that, it's just the story of Keira's life. Well, her freshman year anyway. It's Keira's first year at a new school, without her old friends, and she's freaked out. She's got nobody to talk to, so she begins to write to her old friend Sam. It seems like no big deal, just a few harmless letters to a friend, but Keira isn't sending them. They stay in a pile in her messy room. Why is that? She doesn't want Sam to read them. Why is that? Well, it's for the same reason that Keira is starting a new school this year.
Dear Sam is the story of this troubled teen, how she makes new friends, and how she overcomes the demons of her past that haunt her. I guess there are demons in this story then!
