Depends on what type of poker you want to play.
Try Harrington on Hold 'em 1 by Dan Harrington or Getting Started in Hold'em by Ed Miller.
Super System is mostly good as a piece of history nowadays- some of the games described aren't played any more, and of the others, only Hold'em is played regularly. If you want to learn Hold'em, other books will be better as a starting place.
ok so i wil go for the books u advised me...since i mostly play Hold'em
