Spoilers!
I'm serious. Don't read ahead if you haven't finished the book.

Welp, another great book finished! J.K. Rowling's Harry Potter and the Deathly Hallows was a great concluding book, showing how Harry transforms from a boy into a man. In this book, Harry does not go to school (as he said so in book six), but instead goes into out into the world, searching for Horcuxes.

Horcruxes are plain items, like shoes or little trinkets, but which have been taken up by a part of a soul. For example, if you were to make a Horcrux, you would rip your soul up and place it in whatever item you choose. That way, if you die in your current form, your spirit will end up at the Horcrux you made. It is very dark magic.

Anyways, Harry goes into the forest with Ron and Hermione, whom of which I'm sure everybody is familiar with. He ends up spending countless weeks wondering the forest, which is when Ron, who at the point was wearing the Locket, a Horcrux of Voldemort, gets angry with Harry and leaves. Then, Harry and Hermione repeat the previous process and when Harry sees a Doe Patronus, he follows it to be lead to Godric Griffindor's sword, which is one of the few items in the world that can kill a Horcrux.

I could continue, but whatever.
