A Gambler's Anatomy (published as The Blot in the United Kingdom) is a 2016 novel by American author Jonathan Lethem.
 The plot concerns Alexander Bruno, a professional backgammon player with "psychic tendencies".
 The novel received mixed reviews and was compared negatively to other novels by Lethem.
The Wall of the Sky, the Wall of the Eye is a 1996 collection of seven short stories by Jonathan Lethem.
 In 2002 a collection of the same name appeared in the UK that also contained seven stories, but two stories from the earlier collection—"Vanilla Dunk" and "Forever, Said the Duck"—were replaced by "Access Fantasy" and "How We Got Into Town And Out Again".
 All of the stories, as with much of Lethem's early work, have definite science fiction elements despite their widely varying content and some thinly veiled commentary on modern society.
Jonathan Allen Lethem (LEE-thum, born February 19, 1964) is an American novelist, essayist and short story writer.
 His first novel, "Gun, with Occasional Music", a genre work that mixed elements of science fiction and detective fiction, was published in 1994.
 It was followed by three more science fiction novels.
Diana Athill {'1': ", '2': ", '3': 'OBE', '4': "} (born 21 December 1917) is a British literary editor, novelist and memoirist who worked with some of the greatest writers of the 20th century at the London-based publishing company Andre Deutsch Ltd.
Amnesia Moon is a 1995 novel by Jonathan Lethem.
 Lethem adapted the novel from several unpublished short stories he had written, all about catastrophic, apocalyptic events.
 In finished form "Amnesia Moon" bears homage to Philip K. Dick.
 In fact, during a party scene, one guest describes a battle of wills in West Marin, clearly a reference to Dick's "Dr. Bloodmoney, or How We Got Along After the Bomb".
 One character even cites a West Marin inhabitant named "Hoppington", evocative of the mutant telepath Hoppy Harrington in the latter book.
Motherless Brooklyn is a Jonathan Lethem detective story set in Brooklyn and published in 1999.
 Lethem's protagonist, Lionel Essrog, has Tourette syndrome, a disorder marked by involuntary tics. Essrog works, along with Tony, Danny and Gilbert, who call themselves the Minna Men, for Frank Minna—a small-time neighborhood owner of a "seedy and makeshift" detective agency—who is stabbed to death.
Camden College is a fictional liberal arts college, which appears in the works of Bret Easton Ellis, Jill Eisenstadt, and Jonathan Lethem.
 Whereas Ellis' Camden College is located in New Hampshire, Lethem's Camden is in Vermont, and is notable for being the most expensive college in America.
 All three of the writers attended Bennington College, which is really located in Vermont, and was at one time notorious for being the most expensive college in America.
 Bennington graduate Donna Tartt uses the same Bennington-inspired backdrop for her 1992 novel "The Secret History", but for her it is "Hampden" College.
 However, Eisenstadt and Lethem uses 'Camden' in "From Rockaway" (1987) and "The Fortress of Solitude" (2003), respectively.
Pushcart Prize winner and Best American Short Stories author Mark Wisniewskis third novel, "Watch Me Go" (Penguin Putnam, January 22, 2015), received early praise from Salman Rushdie, Ben Fountain, and Daniel Woodrell.
 Mark's first novel, "Confessions of a Polish Used Car Salesman", was praised by the "Los Angeles Times", the "Chicago Tribune", the "Milwaukee Journal-Sentinel", and C. Michael Curtis of "The Atlantic Monthly".
 Wisniewski's second novel, "Show Up, Look Good", was praised by Ben Fountain, "Kirkus Reviews", "Publishers Weekly", "Psychology Today"' s Creativity Blog, Jonathan Lethem, Christine Sneed, Molly Giles, Richard Burgin, Kelly Cherry, Diana Spechler, DeWitt Henry, and T.R. Hummer.
Judith Hearne (later republished as The Lonely Passion of Judith Hearne), was regarded by Northern Irish-Canadian writer Brian Moore as his first novel.
 The book was published in 1955, after Moore had left Ireland and was living in Canada.
 It was rejected by ten American publishers before being accepted by a British publisher.
 Diana Athill's memoir, "Stet" (2000), has information about the publishing of "Judith Hearne".
A Flag on the Island is a collection of short stories written by V.S. Naipaul, and first published by André Deutsch in 1967.
 It includes the title novella, "A Flag on the Island," outtakes from previous novels such as "The Enemy", from "Miguel Street", and pieces published in periodicals in England or the United States.
 The book is dedicated to Diana Athill.
