Harry Potter and the Half blood Prince is my favourite book among all Harry Potter novels.It is emotional too.After Sirius Black's death Harry had only one person to whom he could talk about Voldemort's matters: Dumbledore.But as he also dies Harry becomes more heart broken.In this book only they find out the way to defeat Voldemort.I like the quidditch matches too.So overall I find this book the best of all and this book is also very appealing.This book is best.Its my favourite.
