My full review is here on my personal website. I'll post a few excerpts here, though:

5.0 out of 5.0 stars

The very worst thing about this book is a toss up between Fred’s death and Snapes’s death. I couldn’t read for almost half an hour because I was crying so hard when Fred died. I know, I’m a crybaby, but I loved Fred and George and their banter. “But we’re not stupid — we know we’re called Gred and Forge.” :-) As for Snape’s death… I cried and cried and then cried even harder when we saw his memories. I still cry at those scenes no matter how many times I read them. Good job, Mrs. Rowling, on the writing. You are a true master.

The very best thing about this book is Snape, Snape, Snape, Snape, Snape, Snape, Snape!!!! I can’t say it enough! SNAPE! If any character Rowling has ever written is to survive time, let it be Severus Snape!! Please, let it be Severus Snape! </end fan-girl-sounding cheer>
