To help out our new friend Feathers: YA Sci-Fi titles anyone?

The "Uglies" trilogy (Uglies, Pretties, Specialsby Scott Westerfeld, I think) is a nicely handled scifi YA premise.

My favorite in recent years is unquestionably the brilliant House of the Scorpion by Nancy Farmer.

H. M. Hoover, Sylvia Louise Engdahl, Madeleine L'Engle

Singing the Dogstar Blues -- Alison Goodman
Feed -- M. Anderson
City of Ember, and its sequels -- Jeanne DuPrau (these skew a little younger)

I was reading plenty of "real" SF as a young adult -- Asimov, Pohl, Clarke, Heinlein, etc. Hands down, my favourite as a teenager was A Canticle for Liebowitz, by Walter Miller.

The Animorphs series, by K.A. Applegate--I know, I know, they're out of print, but they're not that hard to find and they're still good, darnit.

Jane Yolen's Pit Dragon series (Dragon's Blood, Heart's Blood, etc.) is I believe technically sci-fi, as the dragons are all really alien wildlife (like in Anne McCaffrey's Pern series).

The Giver and Gathering Blue by Lois Lowry

Ender's Game is often regarded as the pinnacle in this category.

Thanks everyone, and Feathers, for starting the thread for me. I really appreciate the input.

To be more specific: does anyone know of any YA Sci-Fi books that revolve around superpowers? Thanks bunches.
