In Yalda's universe, light has no universal speed and its creation generates energy.
On Yalda's world, plants make food by emitting their own light into the dark night sky.
As a child Yalda witnesses one of a series of strange meteors, the Hurtlers, that is entering the planetary system at an immense, unprecedented speed. It becomes apparent that her world is in imminent dangerand that the task of dealing with the Hurtlers will require knowledge and technology far beyond anything her civilization has yet achieved.
Only one solution seems tenable: if a spacecraft can be sent on a journey at suffi ciently high speed, its trip will last many generations for those on board, but it will return after just a few years have passed at home. The travelers will have a chance to discover the science their planet urgently needs, and bring it back in time to avert disaster.
Orthogonal is the story of Yalda and her descendants, trying to survive the perils of their long mission and carve out meaningful lives for themselves, while the threat of annihilation hangs over the world they left behind.

Most Helpful Customer Reviews
A compelling plot and lovable, moral characters are the center of this story. There is a fair amount of math in this book, but please don't let it scare you away! You can handle it. Mr. Egan's website has great animations and further descriptions to help. For your efforts you'll be rewarded with no less than a new perspective on the universe. Egan has created a beautiful world, and peopled it with some of the strangest aliens yet imagined. That would be a good book by itself, but Egan has further distinguished himself by a vivid re-imagining of physics itself. This is science fiction at its very best: challenging the reader to see everything in a new light. This book will go down as a classic. As I was reading it, I kept wondering how it could be that I'd never heard of this book before? Only after I finished the book did I realize that it had only been published last month. I'm eagerly awaiting the sequel and enthusiastically recommending it to anyone who'll listen to me.
