In 1349, one small town in Germany disappeared and has never been resettled. Tom, a contemporary historian, and his theoretical physicist girlfriend Sharon, become interested. Tom indeed becomes obsessed. By all logic, the town should have survived, but it didn't and that violates everything Tom knows about history. What's was special about Eifelheim that it utterly disappeared more than 600 years ago?
Father Dietrich is the village priest of Oberhochwald, the village that will soon gain the name of Teufelheim, in later years corrupted to Eifelheim, in the year 1348, when the Black Death is gathering strength across Europe but is still not nearby. Dietrich is an educated man, knows science and philosophy, and to his astonishment becomes the first contact between humanity and an alien race from a distant star when their interstellar ship crashes in the nearby forest. It is a time of wonders, in the shadow of the plague.
Tom and Sharon, and Father Dietrich, have a strange and intertwined destiny of tragedy and triumph in this brilliant SF novel by the winner of the Robert A. Heinlein Award.

Set primarily in the present, with tantalizing flashbacks to the 1800s, In the Country of the Blind concerns a small group of American idealists who managed to actually build the Analytical Engine designed by Charles Babbage and then used it to develop cliology: mathemathical models that could chart the likely course of the future. When their calculations predicted a united Germany armed with unimaginably powerful bombs by 1939, the Charles Babbage Society kept it from ever happening. Soon they were working to alter history's course to their own liking in other ways. By our own time, the Society has become the secret master of the world. But no secret can be kept forever, at least not without drastic measures. When her plans for some historic real estate lead developer and ex-reporter Sarah Beaumont to stumble across the Society's existence, it is just the first step into a baffling and deadly maze of conspiracies.

This is a compelling tale of the glory that was. In the days of the great sailing ships, in the mid-twenty-first century, when magnetic sails drew cargo and passengers alike to every corner of the solar system, sailors had the highest status of all spacemen, and the crew of the luxury liner the River of Stars, the highest among all sailors.

But development of the Farnsworth fusion drive doomed the sailing ships, and now the River of Stars is the last of its kind, retrofitted with engines, her mast vestigial, her sails unraised for years. An ungainly hybrid, she operates in the late years of the century as a mere tramp freighter among the outer planets, and her crew is a motley group of misfits. Stepan Gorgas is the escapist executive officer who becomes captain. Ramakrishnan Bhatterji is the chief engineer who disdains him. Eugenie Satterwaithe, once a captain herself, is third officer and, for form's sake, sailing master.

When an unlikely and catastrophic engine failure strikes the River, Bhatterji is confident he can effect repairs with heroic engineering, but Satterwaithe and the other sailors among the crew plot to save her with a glorious last gasp for the old ways, mesmerized by a vision of arriving at Jupiter proudly under sail. The story of their doom has the power, the poetry, and the inevitability of a Greek tragedy. This is a great science fiction novel, Flynn's best yet.
