David in the Dystopia. In one of Robinson's more subtle - and yet also more obvious - allegories, we find a future where humanity has been reduced to the Stone Age and is clinging to survival by a thread. When one woman is summoned for a quest to stop her only son before he brings humanity to its final end, she is forced to question everything she believes. Yet again, Robinson creates a tale such that only he can, and does it superbly. This one will keep you guessing until the end, and give you one hell of a ride in the process.
