I’ve previously read Orson Scott Card’s Ender’s Game, the day before yesterday I read Ender’s Shadow. It’s not easy to know what to call it, even if Card does give it a try in his foreword of the book:
This book is, strictly speaking, not a sequel, because it begins about the where Ender’s Game begins, and also ends, very nearly, at the same place. In fact, it is another telling of the same tale, with many of the same characters and settings, only from the perspective of another character. It’s hard to know what to call it. A companion novel? A parallel novel? Perhaps a “parallax”, if I can move that scientific term into litterature.
Ender’s Game is about Ender Wiggin, Ender’s Shadow is about Bean. If you liked Ender’s Game, you’ll like Ender’s Shadow. If you liked Ender’s Shadow, you’ll like Ender’s Game: Both books can stand on their own and both complement the other. I liked both books very much.
