Sci-fi book recomendations

Oh holiday last year I read the book "I am number 4", recently saw the film and was so dissapointed as the book was AMAZING. Got the sequal for christmas "The power of six" and have just started reading it. Loving it from the very start and I feel like im really getting back into reading after such a long time.

Just wondering if any of you out there have read these books and can recomend what to go for next?

Raymond E.Fiest has some good books, i recomend Magician its a really good book, time travel ect, going to different planets.

all depends on what style of SF writing you like.

Not exactly sci-fi but suprisingly good.

My brother gave me the first two books in the series I read book one and enjoyed it, a nice easy read with an unusual twist.

Slaughterhouse Five by Kurt Vonnegut.

Use of Weapons - Iain M. Banks

The reality dysfunction - Peter f. Hamilton.

I hav2 2 sci-fi books going on my Amazon Kindle app on my Android at the moment, HG Wells' War of the Worlds and Star Wars: Shadows of the Empire, both excellent and well worth reading IMO.

Use of Weapons - Iain M. Banks

that is a good book.

Ive always like the 'Robot' stories by Isaac Asimov.

2001: A Space odyssey is one of the greats.

Ringworld, Larry Niven. Although you might want to read some of his other stuff first, as a sort of lead in. Followed by Ringworld Engineers.
