Took me a while to slog through all of it, but I just finished "Eclipse" by Stephenie Meyer.
After really liking "Twilight" (the first book in the Twilight series), pretty much liking "New Moon" and now a little bit liking "Eclipse", I think I'll take a Stephenie Meyer break before reading the conclusion to the series... "Breaking Dawn".
I shouldn't be too critical, though, as the book really isn't written for me, but rather primarily for teenage girls (and as such is very heavy on relationship melodrama). That said, I enjoyed quite a bit the first half of the original book as the anticipation and suspense building was solid. I'm sure I will finish off the series at some point, just not soon.
