Birthday in two weeks, parents said i could buy some books but i can't find any books?! Recommendations please?

I love my fantasy books! I just can't get enough of them. I've read the books Shiver and Linger (series), The Immortals Series, Twilight saga, (currently reading) Fallen (waiting to read Torment) Sookie Stackhouse series, House of Night series, Night World series... The list goes on! But the thing is i actually don't know what other books i would like to read. I've gave you a few guide lines on what books i love to read. Could anybody give me recommendations for any great fantasy books similar to these?
