Recently I must read complete boook, but then I get lost cause I'm not intesrted can you help, I read all the harry potter books and those are my favorites, but I don't like Lord of the rings, I heard about a book twilight that's good and I like books with cool plots like harry potter or if it exists a Final Fantasy or Zelda book describing the plot, please comment help me find one.

God no stay away from Twilight, it's garbage.

If you want good fantasy, start with these:
Dragonlance Chronicles set (read the fourth book after the Legends series please nevermind, the 4th doesn't come in that set, doesn't matter, it's not that great anyways)
Dragonlance Legends set

After you're done with those, get this:
The Dark Elf Trilogy

If you're looking for something more lighthearted, read the More Than Complete Hitchhiker's Guide (which should be required reading anyways).

But Jesus just stay away from Twilight.

-edit-

Well that's a shame, the More Than Complete Hitchhiker's Guide I linked to is out of print (though you can still get it on Amazon).  If you don't want to get that, you can still get all the books by themselves. 

I repeat-- these books should be required reading for everybody.

You can't not like them.

an interesting twist on a classic tale is teh frankenstien series from dean koontz

Just imagine if Victor Frankenstein was alive today, building new race citizens in a bid to take over the world which he deems inferior to replace it with his master race, the only thing standing in is way is a small group of humans led by his first and most powerful creation while the rest of the world is unaware of the monsters lurking in their own backyard

Discworld.

It uses a fantasy world to satirise ours (never dull like LotR). Its humour is brilliant and intelligent. Read Witches Abroad, or Mort. There's more than 20 books in the series, almost all of which are top quality.

Do NOT get Twilight.
