The Observers. CV Book 2

McNulty's Disease has escaped the Sea Venture and is now epidemic on land. The disease kills only a few of its victims...but no one knows what long-term effects it has on those who survive. For the public's safety, the U. S. government sets up a giant internment camp on the old CV herself, and attempts to find as many survivors as possible to keep safely on board the ship. Fortunately, Julie Prescott has a most resourceful and clever husband (he used to be a high-priced hired killer) who doesn't want his wife locked up forever.
So he sets himself up against the entire government bureaucracy - with remarkable results.
