I’ve been slammed at work, so not much time to say much of anything.

But I will offer a recommendation for The Windup Girl.

Not quite post-apocalyptic, but definitely a vivid and believable bit of world building (critical to any good sci fi or fantasy novel) for an earth after global climate change and made it suicidal to continue to use fossil fuels, coastal cities either used to be inland or are protected by high sea walls, and “calories” (as in both food calories, but also calorie meaning a measure of any form of energy) become the source of power.

It’s sort of like Neuromancer for the Audubon Society set.
