The Overstory by Richard Powers - an intertwining of lives, as witnessed by the oldest beings on Earth, putting things into a rather different perspective.
The Windup Girl by Paolo Bacigalupi - compassion and redemption, set in a terrifyingly plausible near future where the oil and tech companies have been replaced by gene and agro conglomerates. Calories or joules, it’s just energy.
Weaveworld by Clive Barker - a dark, fantastical yarn of vivid (sometimes grotesque) imagery, spinning a new take on the oldest tale, that of good vs. evil.
