Harry Potter and the Sorcerer's stone

The title of my book is Harry Potter and the Sorcerer's Stone. I chose this book because I've seen the movies so i thought i should try the book as well. the protagonist are Harry, Ron and hermione. the antagonist  right now seems like it would be professor Snape. The main conflict right now is they are trying to find out why Snape was trying to get past the dog, and who Flamel is. A theme of my book would be always have courage. the best part in my book is when  Harry catches the snitch in his mouth because he won the game for griffendor and he showed bravery. IO would rate this book a 10 because it keeps me interested and i want to keep reading it.
