Hey! I know what you mean, after reading the Twilight saga its hard too try and find something else. There are the Night World books by L.J Smith and the books by P.C and Kristin Cast they are all really good.
Just some suggestions :)
The Time Traveler's Wife by Audrey Niffeneger.. i don't know how old you are though, that's definitely an older than 16 read I think...
Nicholas Sparks rights really good romance books - The Wedding follows one of the son in laws of Noah and Allie from the Notebook which he also wrote.... and Nights in Rodanthe is good also....
some of my other favorites:
Angels in America by Tony Kushner
Angels & Demons & The Davinci Code by Dan Brown
Catcher in the Rye by J. D. Salinger
My Sergei by Ekaterina Gordeeva
Five People You Meet in Heaven by Mitch Albom
The Fountainhead by Ayn Rand
The Great Gatsby by F. Scott Fitzgerald
The God of Small Things by Arundhati Roy - this one is a really sad book about twins growing up in India, but its good
Thanks. Someone else suggested The Time Traveler's Wife, I'll definitely look into it. Nicholas Sparks: I have all of his books. The Wedding is the best! and thanks for your other suggestions, I will definitely look into them!
