PULITZER PRIZE WINNER • Drawing on the diaries of one woman in eighteenth-century Maine, "A truly talented historian unravels the fascinating life of a community that is so foreign, and yet so similar to our own" (The New York Times Book Review). Between 1785 and 1812 a midwife and healer named Martha Ballard kept a diary that recorded her arduous work (in 27 years she attended 816 births) as well as her domestic life in Hallowell, Maine. On the basis of that diary, Laurel Thatcher Ulrich gives us an intimate and densely imagined portrait, not only of the industrious and reticent Martha Ballard but of her society. At once lively and impeccably scholarly, A Midwife's Tale is a triumph of history on a human scale.

In 1969, the first two men landed on the moon. There were five other landings, leading to a total of twelve astronauts standing on the moon. A further six circled above while the world watched. Also in 1969, Sir Robin Knox-Johnston was the first man to sail solo non-stop around the world south of Cape Horn. He was the eighth of only eleven men who rounded the Horn alone before the final moon landing. Those eleven men had no-one watching them.This dramatic and exciting book, written so vividly you can feel the sea's spray on your face and taste the salt on your lips, tells the story of the lives of those eleven men and their sailing exploits, and compares and contrasts their voyages with what the twelve space astronauts achieved.'One famous astronaut spoke of "e;a small step for man, one great leap for mankind"e;. For those who go to sea, rather than into space, there's no greater step than rounding the Horn.'From the preface, written by Paul Heiney
