Harry- He doesnt think he will be able to attent his potions NEWT class but since there is a new teachre he can. Since he didnt think he would be able to attend he didnt buy his books, the teachre lends him a book but it has writing all over it. During a contest harry decides to follow the instructions written down by the previous owner and to his suprise they work extremely well. little does he know the book belonged to someone hes always hated.

Hermione- Shes jealous of harry because hes getting all the attention and shes basically rude throughout the book. she tried to find the name “prince” in the old hogwarts photos and discovers the mother of the books owner.

Ron- Since harry was appointed captain of the gryffindow quidditch team ron trys out. he saves 5 out of 5 goals and is appointed keepper. Though throughout every game he has a case of the nerves and loses points because he gets nervous.

Dumbledore- Gives harry private lessons to tutor him on voldemorts past. Also tells harry how to kill voldemort by destroying his 7 horcruxes ( a horcrux is when u detatch a part of ur soul and put it in an object or animal)

Snape- ahhh where to begin…..The previous owner of the book harry found. the one who kills dumbledore. a double double agent. basically hes a dick throughout the book but he redeems himself in the next one.
