The late, great Sir Terry Pratchett (1948–2015) famously had his hard drive crushed by a steamroller after his death to prevent the posthumous publication of any unfinished work. Now, however, “uber-fans” Pat and Jan Harkin have unearthed a treasure trove of Pratchett’s early writing published in the 1970s under the pseudonym Patrick Kearns. The result: a collection of 20 excellent, often laugh-out-loud early works. Pratchett’s fans will be particularly delighted with “The Quest for the Keys,” which contains the first mention of the Discworld series’ Morpork, as well as the set of short stories focusing on Father Christmas leaving a job vacancy—“Wanted: A Fat, Jolly Man with a Red Woolly Hat” and “The New Father Christmas”—which will remind readers of Pratchett’sHogfather. The collection also includes a touching foreword from Pratchett’s good friend andGood Omens collaborator Neil Gaiman, and a concludng essay from the Harkins explaining their methodology and their discoveries. Pratchett devotees will be moved and gratified by this unexpected gift and even casual readers will be utterly charmed. There isn’t a bad story in the bunch.(Oct.)
