Ender's Game - Orson Scott Card
“There are miracles even relativity can’t pull off, Ender.”

I love this book! I didn't expect it to be this good. I love how you could be emotionally stressed and invested with all the twists and turns of events and what Ender feels in every page. Aaaaand, I love anything sci-fi!

(I'm in doubt if i should read the sequel because i loved the ending and i'm afraid the sequel might not give justice to the first book)
