Can you suggest me a good Sci-Fi book?

Hey there!

I’m a fan of Sci-Fi literature. Last book I have read (one of the greatest ever, too) was Hyperion. I was pretty impressed by the story of Lt. Kassad. I really loved the way the whole space battle was described ! (in fact, i was amazed/stunned by the vivid description of the whole thing, the bone-chilling feeling induced by the medical area corridor, a.s.o.) Can anybody suggest me a good Sci-Fi book that is centered/describes such things?

Thanks :D !
