Demon Glass

I just finished a book called Demon Glass, by Rachel Hawkins. The book was the second in a series, and it was about a girl, named Sophie Mercer, who just found out that she was a demon, which is supposed to be a vicious creature that attacks people. And her dad, the head of a council that protects people like Sophie, is one too. Sophie also found out that she and her dad were the only demons left in the world. But Sophie's dad left her and her mom when Sophie was a little baby, so when her dad asked her if she would like to spend a summer with him in England, to learn more about being a demon, she didn't hesitate to say yes. But when she gets to the mansion that she, her dad and the council are staying at, she realizes that she and her dad aren't the only demons there. As the book goes on, Sophie helps her two new friends, also demons find their creator, or the one who turned them into demons, and she is surprised at what she finds out.
