Red Mars by Kim Stanley Robinson is astounding, the benchmark.
The Space Merchants (Kornbluth/Pohl) is an oddball novel about a hyper-consumerist future, where the settlement of Venus is driven by marketing. It's all about an advertising executive.
As a note, Red Mars is the first volume of a trilogy (there's also Green and Blue Mars). It is quite hard SF with systems that are or were considered as solution for Mars terraformation, very good recommendation !

Both highly recommended, for different reasons.
