And a nice way to bridge genres. (If you missed it, the book is called Never Let Me Go and is by Kazuo Ishiguro.)

I also suggest Raymond E Feist's Magician and the subsequent books, as well as the series he wrote with Janny Wurts.

Read To Ride Hell's Chasm by Wurts.

Try some Alistair Reynolds.

And for a not-fantasy-at-all pick, I suggest The Kite Runner by Khaled Hosseini, or The Reluctant Fundamentalist by Mohsin Hamid.

Or The Life of Pi by Yann Martel.
