This book is an enthralling read, charting the progress of a young boy, Ender, with an innate genius for tactical violence, who enters a harsh military academy (set in the future) where he participates in a gruelling selection process which whittles him down to take control of the remaining of Earth's space forces in a last ditch attempt to defeat an alien race that is threatening Earth's existence.

The characters are realistically set, evoking sympathy and empathy from the reader and the plot enables you to completely emerse yourself in Card's future world. The technology is believeable and the twist at the end is well worth the read.
