"John Harrow doesn't exist, and his job is to make sure that other things don't exist, too. At any given time, the government is running dozens of black book operations, experiments that aren't on any official record and are never acknowledged to exist. Some of these are innocuous. Some of them are monstrous beyond reason. And most of the time, they go as expected and the public is never the wiser. Most of the time. John Harrow's job is to handle them when things go wrong, and do anything to make sure the government's secrets stay just that--secret" -- provided by publisher.
