Johnny is a courier. He carries other people's memories, millions of them, downloaded into his brain... Working out of Beijing, he is hired to carry a package to the States. The hundreds of gigabytes stashed in his head are far beyond his capacity, but as long as he gets downloaded quickly they won't do him any permanent harm...

Anders Jensen is having a bad month. His roommate is a data thief, his girlfriend picks fights in bars, and his best friend is a cyborg…and a lousy tipper. When everything is spiraling out of control, though, maybe those are exactly the kind of friends you need. In a world divided between the genetically engineered elite and the unmodified masses, Anders is an anomaly: engineered, but still broke and living next to a crack house. All he wants is to land a tenure-track faculty position, and maybe meet someone who's not technically a criminal—but when a nightmare plague rips through Hagerstown, Anders finds himself dodging kinetic energy weapons and government assassins as Baltimore slips into chaos. His friends aren't as helpless as they seem, though, and his girlfriend's street-magician brother-in-law might be a pretentious hipster—or might hold the secret to saving them all.
