This book follows 17-year-old Harry Potter, who is trying to defeat Voldemort while he still has the chance because Voldemort is planning to take over the Ministry of Magic and Hogwarts. Then, he plans on creating trouble in the non-wizardry world which is a normal world with humans like us.
So, Harry, Ron and Hermione start a mission to go find and destroy partsof Voldemort's soul, the Horcruxes. This group of three must rely on each other because they can no longer trust anyone else, but Ron gets frustrated at their slow progress of destroying the Horcruxes, and then he surprisingly leaves the group.
This book is full of memorable parts, like in one, Harry learns that he has to die in order to defeat Voldemort, so he walks CALMLY into the forest, where Voldemort patiently waits to kill Harry Potter.
With the ultimate finale better than expected, this book is a must read. So I'm going to go with 4/5 stars for Harry Potter & The Deathly Hallows.
