It was okay in my book. From a writer's standpoint, I couldn't stand it; Meyer seems to love the classic bait-and-switch. (Oh, Bella, I can't love you... But I guess I can.) She also uses a lot of deus ex machinii(?) in her books, it seems. A lot of the series seemed forced in my eyes. From a reader's standpoint, I was pretty unimpressed. A lot of the story is very cliche (vampire romance? with a vampire werewolf war?) but it reads nice and fast.
I hate hate hate Bella, though. Too whiney and prissy for my taste. (Oh, Jacob, Edward has abandoned me! I'll be your best friend and possible romantic interest... JUST KIDDING! I STILL LOVE EDWARD THE SECOND HE REAPPEARS)
All in all, It's a decent read in my eyes. There's always better stuff, but there's always worse stuff.
(On another note, my opinions may be biased as I'm the primary Twilight "Devil's Advocate" in my friend circle, meaning I play the part of being totally against it.)
abrupt end. (which isn't actually that abrupt. D
