Offshore possesses perfect, very odd pitch. In just over 130 pages of the wittiest and most melancholy prose, Penelope Fitzgerald limns the lives of "creatures neither of firm land nor water"--a group of barge-dwellers in London's Battersea Reach, circa 1961. One man, a marine artist whose commissions have dropped off since the war, is attempting to sell his decrepit craft before it sinks. Another, a dutiful businessman with a bored, mutinous wife, knows he should be landlocked but remains drawn to the muddy Thames. A third, Maurice, a male prostitute, doesn't even protest when a criminal acquaintance begins to use his barge as a depot for stolen goods: "The dangerous and the ridiculous were necessary to his life, otherwise tenderness would overwhelm him." At the center of the novel--winner of the 1979 Booker Prize--are Nenna and her truant six- and 11-year-old daughters. The younger sibling "cared nothing for the future, and had, as a result, a great capacity for happiness." But the older girl is considerably less blithe. "Small and thin, with dark eyes which already showed an acceptance of the world's shortcomings," Fitzgerald writes, she "was not like her mother and even less like her father. The crucial moment when children realise that their parents are younger than they are had long since been passed by Martha." Their father is farther afield. Unable to bear the prospect of living on the Grace, he's staying in Stoke Newington, part of London
