While you're waiting for Micro, I would suggest reading Richard Preston's 1997 novel The Cobra Event. Excellent read, plus it’s a way to acclimatize to Preston’s style before reading Micro.
From Publisher’s Weekly review of The Cobra Event:
“this exciting tale of bioengineered viruses on the rampage leans on the sort of cool, fact-packed prose usually associated with nonfiction--or with the sort of cautionary science thriller aced by Michael Crichton. Like Crichton, who's an obvious influence, Preston knows how to explode from the gate: his opening, in which a schoolgirl attacked by an unknown virus spasms and bleeds and eats her own lip, will plunge readers into shock.”
