JK Rowling's "secret" crime novel has topped book charts after it was revealed she had written it under a pseudonym.
The Harry Potter novelist published the book - The Cuckoo's Calling - as Robert Galbraith.
The book had sold less than 500 copies before the secret emerged in the Sunday Times, according to Nielsen BookScan's figures.
Within hours, it rose more than 5,000 places to top Amazon's sales list.
The digital version is now also at number one in the iTunes book chart.
The book was published by Sphere, part of Little, Brown Book Group which published Rowling's first foray into writing novels for adults, The Casual Vacancy.
Little, Brown's David Shelley confirmed to The Bookseller the publisher had ordered an "immediate reprint" with the number not yet confirmed.
Rowling said she had "hoped to keep this secret a little longer".
The author described "being Robert Galbraith" as "such a liberating experience".
The Cuckoo's Calling
Cormoran Strike is a down-on-his-luck private investigator, with few clients, in debt, just coming out of a breakup, and living in his office. A former soldier in Afghanistan who lost his leg to a land mine, Strike is hired by John Bristow, the brother of famous supermodel Lula Landry, called the Cuckoo by her friends. Bristow wants Strike to investigate his sister's supposed suicide: she fell to her death several months prior. In investigating the case, Strike moves in glamorous tiers of society previously closed to him.
