Blue Skies is a great start to Matthew Mather's Atopia Chronicles. In just a few pages he introduces you to believable future and a character I immediately identified with.
Olympia is an advertising exec run out of steam, but she can't admit it. She is past the edge of a nervous breakdown and needs to find some control. She doesn't like to use drugs but agrees to test a new technology, nanobots embed 'smaticles' into her nervous system and give complete control over the reality she perceives — bots aren't drugs! With the help of her new poly-synthetic sensory interface, or "pssi," Olympia learns one of those "be careful what you wish for" lessons.
