Owen Meany is a dwarfish boy with a strange voice who accidentally kills his best friend's mum with a baseball and believes—correctly, it transpires—that he is an instrument of God, to be redeemed by martyrdom. John Irving's novel, which inspired the 1998 Jim Carrey movie Simon Birch, is his most popular book in Britain, and perhaps the oddest Christian mystic novel since Flannery O'Connor's work. Irving fans will find much that is familiar: the New England prep-school-town setting, symbolic amputations of man and beast, the Garp-like unknown father of the narrator (Owen's orphaned best friend), the rough comedy. The scene of doltish Dr Dolder, Owen's shrink, drunkenly driving his VW down the school's marble steps is a marvellous set piece. So are the Christmas pageants Owen stars in. But it's all, as Highlights magazine used to put it, "fun with a purpose". When Owen plays baby Jesus in the pageants, and glimpses a tombstone with his death date while enacting A Christmas Carol, the slapstick doesn't change the fact that he was born to be martyred. The book's countless subplots add up to a moral argument, specifically an indictment of American foreign policy—from Vietnam to the Contras.

The book's mystic religiosity is steeped in Robertson Davies' Deptford trilogy, and the fatal baseball relates to the fatefully misdirected snowball in the first Deptford novel, Fifth Business. Tiny, symbolic Owen echoes the hero of Irving's teacher Günter Grass's The Tin Drum—the two characters share the same initials. A rollicking entertainment, Owen Meany is also a meditation on literature, history and God. —Tim Appelo

The Fourth Hand is one of John Irving's finest novels to date. A man loses his hand. His search to become whole again soon makes him realise that it takes more than a new limb to find fulfilment. The novel begins with one of Irving's typically surreal scenarios: "Imagine a young man on his way to a less-than-thirty-second event—the loss of his left hand, long before he reached middle age." The unfortunate young man is the "irrefutably good-looking" television journalist Patrick Wallingford. While filing a report from a circus in India, Wallingford's left hand is eaten by a lion. Millions on TV watch the grisly scene. As friends and former lovers watch the disappearance of the reporter's hand, it becomes clear that:Patrick Wallingford initiated nothing, yet he inspired sexual unrest and unnatural longing—even as he was caught in the act of feeding a lion his left hand. He was a magnet to women of all ages and types; even lying unconscious, he was a danger to the female sex

Bereft of his left hand, Wallingford ("the lion guy") finds that both his career and his already active sex life blossom. But "Dr. Nicholas M. Zajac, a hand surgeon with Schatzman, Gingeleskie, Mengerink & Associates", soon seduces him with the offer of a hand transplant. Unfortunately, "there were some strings attached to the donor hand" in the shape of its former owner's widow, Mrs Clausen from Green Bay, Wisconsin. Wallingford soon discovers that the transplant is only the beginning of his problems, as he goes in search of what transpires to be his "fourth hand". The Fourth Hand is a wonderfully funny and compulsive novel, which manages to encapsulate Irving's hallmark black humour with an incredibly tender pathos and gentle wisdom. Wallingford is a marvellous, flawed protagonist, a foolish, vain but ultimately decent man, while Zajac is one of Irving's finest comic creations. Above all, The Fourth Hand is a wonderful and lyrical love story, which is destined to become a classic. —Jerry Brotton
