Harry Potter and the Deathly Hallows: JK Rowling. Re-read. This is definitely the Harry Potter book I've read the least (this is only my second time through it.) It has some definite rambling I could do without (most of the time between when they start running and finally destroy the locket Horcrux), but overall I just love it. The Battle of Hogwarts is just epic. I shed a tear again this time when Hedwig dies and for Fred. I love Neville's underground resistance movement.
