Ooh, loads! Ender's Game is a great classic.

Others include:
Rick Yancey's The 5th Wave
R.C. Lewis's Stitching Snow
Kat Zhang's What's Left of Me
Beth Revis's Across the Universe
Amie Kaufman's These Broken Stars
Scott Westerfeld's Uglies

They're all rather popular series so you should have no trouble finding it in a library/ bookstore/ online/ whatever works for you x

yeah I like space related YA books too (like across the universe and these broken stars) any recommendations ?

I think I've posted earlier on this thread... maybe? Anyway, I suggest Sky Chasers by Amy Kathleen Ryan.

Someone earlier had mentioned 'good superheroes' books in relation to this topic. I'm surprised no one has chimed in yet with R J Ross's "Cape High" YA series. I am getting a big kick out of them, especially the way they spoof "real" superheroes.

Lexie Dunne's Superheroes Anonymous and Supervillains Anonymous (Don't read the first one until you have the second one as the first ends on a real cliffhanger) are perhaps not technically YA as the protagonists are in their early 20's but they almost come across as YA to me in style and angst level.

And I can't mention YA and Sci-fi and not think of Diane Duane's Young Wizards books, which are currently getting updated to be more relate-able to today's youngsters. And yes, they are magic but they are still sci-fi as well.
