Ive not read twilight and i dont normally read fantasy books (i assume they're fantasy from what ive seen on MN) but htese two series are brilliant:
The Chronicles of Thomas Covenant the Unbeliever by Stephen R Donaldson.
and the GAP series by the same author...these are the best most gripping books ive ever read. At teh time i read them he was writing them so i had to wait months for the next installment and then buy it hardback as i couldnt wait for the paperback.
dd got a trilogy which I read during my holiday about underworlders, spirits, werewolves, vampires etc. I quite enjoyed it! Can't remember author, but they were City of Bones, City of Ashes, City of Glass
