if you like the fantasy aspect of twilight try harry potter 1,2,3,4,5,6,7..
if you like the sexual tension aspect try The Other Boleyn Girl
Both of these books are extremely suspenseful just like twilight. if you've already read them and liked either of them let me know and I can tell you other ones from those categories which are good. I know the books I listed are very long but if you read twilight I don't see why that should be a problem...
my friend likes the vampire diaries but haven't read them/it. I read twilight and new moon. funny love stories- one for the money by janet evanovich. it's a (stephanie plum) series of 14 books, the 13th is my favorite. considered mystery but it's romantic comedy with a dash of mystery. I'm totally addicted, have read all fourteen. some two and three times.
i don't know about love but I know some great series! =P there is the ranger apprentice series and the warrior series! very good books. their is also a book called the challenge... its got major love stuff going on and it has a couple of sequels... animorphs is sort of a smal chapter book but its a series I loved it.
Try out The Lovely Bones...it's really very sweet after you get through the beginning
Well I really don't like Twilight at all, but if your in to cute love stories, there are some Sarah Dessen novels that you might like. I love basically all of her books, but my favorites are Lock and Key, Someone Like You, Dreamland, and Just Listen. Check them out :)
