-If you haven't read book one and two do that first- \\Book 3// I'm Lyla Potter and this year I go into my third year at Hogwarts school of Witchcraft and Wizardry. I have my brother Harry Potter, my two best friends Hermione Granger and Ron Weasley and my newly found boyfriend Dean Thomas. I can just feel that this year is going to bring fun and games. But with the presumably convicted murderer Sirius Black on the loose Harry's going to have trouble. I on the other hand have a person to confide in.
