"Little Brother" by Cory Doctorow

This book has it all - computers, video games, hacking. I'm not into any of these, but I still LOVED this book! San Francisco - terrorists blow up the Bay Bridge. People are scared, and the government starts using high-tech surveillance to "protect" its citizens. Marcus and his friends discover this new system isn't foolproof and innocent people are being interrogated and held prisoner. There is excellent discussion on security versus civil liberties, as well as romance, raving and gadgets galore. Scott Westerfield described it best - “A rousing tale of techno-geek rebellion.” One of the best books I've read this year, and I don't even like science-fiction!

"Ender's Game" by Orson Scott Card

Ender Wiggin is an extraordinary game player. His brain is so sharp and brilliant that he's been chosen to attend a prestigious Battle School, where students are trained in military combat. It's the future, and planet Earth is preparing for an invasion against the buggers - alien lifeforms that are determined to destroy our planet. Using high tech computer games to simulate fights and battles proves to be intense and exhausting. Every move Ender makes must be perfect, the future of the universe depends on it! Great science fiction writing.
