The punch escrow

the long version

"It's the year 2147. Advancements in nanotechnology have enabled us to control aging. We've genetically engineered mosquitoes to feast on carbon fumes instead of blood, ending air pollution. And teleportation has become the ideal mode of transportation, offered exclusively by International Transport--the world's most powerful corporation, in a world controlled by corporations. Joel Byram spends his days training artificial-intelligence engines to act more human and trying to salvage his deteriorating marriage. He's pretty much an everyday twenty-second century guy with everyday problems--until he's accidentally duplicated while teleporting. Now Joel must outsmart the shadowy organization that controls teleportation, outrun the religious sect out to destroy it, and find a way to get back to the woman he loves in a world that now has two of him."--Jacket flap.
