HarryPotter and the Deathly Hallows
Why its good
HP is a really good book because it is an ending to a seven-part series that was incredible, and doesn't change the setting each book. The Deathly Hallows is the very end of and the game changer of the HP series,the best series I've ever read.
Harry's big problem is that an old dark wizard who no one names is after him. He wants Harry dead because of something that happened long ago. And tries to kill him in all sorts of different ways. Wizardry and Witchcraft galore Hogwarts hurt and destroyed connections lost and totally being cut off.
I would say that out of the entire Harry Potter series the best of them is the one that fantasy lovers should all want to read,the Deathly Hallows. But the last books about the magical world are Fantastic Beasts and Where to find them and Quidditch through the Ages just in case you finish the entire HP series to fast.
J.K Rowling is the author of several books like The Casual Vacancy ,Pottermore,Fantastic Beasts and Where to find them,and Quidditch through the Ages
