...the book is called Harry Potter and the Deathly Hollows.
did the spell-check do this?

i believe it will be
Hallows instead of
Hollows. although it would make sense if JKRowling uses the latter, with the mention in previous books in the series about
Godric's Hollow -- where Harry's parents James and Lily last hid themselves away from He-Who-Must-Not-Be-Named.
i'm pretty much excited about this final installment in the harry potter series myself -- to read how JK Rowling would tie up all the loose ends in the previous ones, like how it would be explained who
really died first (James or Lily) as exhibited in the scene when Harry battled with Voldemort and the "souls" of the people killed by Voldemort's wand were spouted from within to help protect Harry (the sequence of which runs opposite to what JK Rowling wrote beforehand).
anyway, that's just a minor point and there are much more exciting adventures, characters and scenarios to watch out for, like Professor Snape's
true personality which we all encountered as seesaw-ing between good and evil. inspite of his bad reputation through the eyes of Harry (and others), i hope he will be redeemed in this final book and not be one among the two significant characters who will eventually meet his/her demise. i also wish Dumbledore gets "resurrected" in this book seven (i don't believe he actually died in book six... there are some tell-tale signs dropped in the book by JK Rowling which may hint on his being still alive). and hey, there are all sorts of MAGIC abounding the series, so this could be one of them.
