“Lanchester's book is also noteworthy for a splendid choice of language and metaphor not usually found in writing on economics and finance…All economic writing should be so evocative.” —Benjamin M. Friedman, The New York Review of Books

“Warning to bankers everywhere in the world. You better buy every single copy of I.O.U. because Lanchester’s painted the target on you that the rest of us so desperately wanted to see." —James J. Cramer, host of CNBC’s Mad Money

“Few if any [finance] books will be as pleasurable—and by that I mean as literate or as wickedly funny—as John Lanchester's…Before you begin to cry, pick up a copy of I.O.U. Good humor and good company will be the things that’ll get us through.” —Dwight Garner, The New York Times

“Lanchester's gift is to see the big picture in new ways.” —Dennis Drabelle, The Washington Post Book World

“[T]his elegantly crafted little book…manages to be, by turns, acidic, frightening, and sharply funny. What it is not is boring….it all makes perfect sense. A.” —Tina Jordan, Entertainment Weekly

"Lanchester understands perfectly that the man behind the curtain was no wizard–that markets, far from being God-given instruments of perfection, were human constructs. ...[He] is adept at explicating financial complexities with street level analogies."–Roger Lowenstein, NewRepublic.com

“Witty, lucid, solicitous of the average person's difficulty in grasping the conceptual underpinnings of international finance....Lanchester manages to know enough to explain the terrain clearly and yet he never loses his perspective…Lanchester had me in the palm of his hand…” —Laura Miller, Salon.com

“[A] writer with literary bona fides…[Lanchester] has the intellectual heft and the chops, as a jazz musician might say, to deliver a resounding book about the crisis….An elegant and wonderfully witty writer, Mr. Lanchester approaches his subject with a newcomer’s verve. It’s infectious….frame[s] the Great Recession in startlingly original terms.” —Devin Leonard, The New York Times, Sunday Business

“[Lanchester] brings his mischievous wit to bear on the Great Credit Crackup in his boisterous primer….His method: to boil complex instruments and linkages down to anecdotes, outlandish images and acerbic asides that strip away those layers of bank jargon. The result is the perfect read for anyone still wondering what went wrong and why.” —James Pressley, Bloomberg News

“In I.O.U., the only truly entertaining book I've read on the subject, the British writer John Lanchester theorizes that after the Cold War, capitalism could go wild because Western governments no longer had to worry about competing with communism. This is a fascinating idea…” —Jacob Weisberg, Newsweek

“The novelist John Lanchester’s short book on the finance crisis, I.O.U.,…is literary and profound….But this is not just finance-for-poets. Lanchester…is a master explainer with an excellent grasp of sophisticated finance. His book is a gem.” —Christopher Caldwell, The Daily Beast

"I.O.U. is the map to the crazed world of contemporary finance we have all been waiting for. John Lanchester's superb book is everything its subject, the 2008 crash, was not: namely lucid, beautifully contrived, comprehensible to the reader with no specialist knowledge—and most of all devastatingly funny. I urge you to read it." —Will Self, author of Liver

“Hard to imagine any book giving us a clearer, more concise overview of the global financial crisis. I.O.U. is endlessly witty, for one thing, but the wit is underpinned by a tremendous, unembarrassed anger and moral lucidity. A superb entry-level guide which will turn any reader into an expert within the space of 200 pages.” —Jonathan Coe, author of The Rotter’s Club and The Rain Before It Falls

“I.O.U. is so clear and funny and cleverly written. I love the personal asides and observations and jokes and bits of autobiography that make it seem human and not text-book like. And the more and more improbable analogies for the ups and downs of the markets (a bride's nightie...a gorilla on a pogo stick). But what I like most is that it makes me feel intelligent, because I can now understand all this stuff.” —Marina Lewycka, author of A Short History of Tractors in Ukrainian

“From the insane and apparently incomprehensible chaos of the financial meltdown John Lanchester has extracted a compelling narrative, clearly explaining the madness of modern capitalism with razor-sharp insight, brilliant clarity and a refreshing dose of humor. A great book; interesting, accessible and witty.” —John O’Farrell, former columnist for The Independent and The Guardian, and author of An Utterly Exasperated History of Modern Britain: or Sixty Years of Making the Same Stupid Mistakes as Always
