Harry Potter and the Deathly Hallows by JK Rowling

The best selling book on record, like the other two or three before it. And I can see why. There aren't any questions apart from minor ones (we all want to if Dobby gets married to Myrtle, I know, but it's totally irrelevant. Through an adventure, a mystery, a comedy, a romance and more, the brilliant scene at the end we've all been waiting for comes - a little thing that  includes a battle at Hogwarts. Will Harry live or die? Well, the answer to that question was just amazing. People wanted Harry to live and Harry to die. Go read this book, as they'll be doing in hundreds upon thousands of years. 10/10
