Ender's Game, by Orson Scott Card is one of the best books ever written in sci-fi, as well as the succeeding books in this series. I find this book as a real page turner. Orson Scott Card writes the characters in such a way that they are alive. The 384 page book will provide you with an intense experience. It has depth, and it's not just a story written for the sake of a story. It has caused me to reflect a lot.
Brief Summary of Ender's Game
Ender's game is set in the future, where Earth and humanity is threatened by an insect-like alien race that humans called Buggers. The Bugger's first invation was thwarted by the genius Mazer Rackham, but another invation may come. Humanity has trained children to become the next leaders, but this time, it isn't to defend Earth, but to go in an all out attack against the Bugger homeworld.
Not only for sci-fi fans, but for all types of readers
Definitely worth your money! Even if you're not a sci-fi fan, this book is definitely worth trying out. The core of Ender's game is not in it's sci-fi plot, but in its philosophy. It is not something off this world and unapplicable, as it applies to our current world.
