Fewer than 24 hours after it was revealed that J.K. Rowling used the pseudonym Robert Galbraith for the crime novel The Cuckoo's Calling, the book was #1 on Amazon and backordered for 10-14 days. It was #20 in the Kindle store and #1 overall in print on Barnes & Noble. The Cuckoo's Calling was published by Little, Brown's Mulholland Books on April 30, 2013 and through last week had sold about 500 copies at outlets that report to Nielsen BookScan. Cuckoo's is available as an e-book.

Rowling was discovered by the Sunday Times in investigating "how a first-time author with a background in the army and the civilian security industry could write such an assured debut novel." In a statement, Rowling said: "I hoped to keep this secret a little longer because being Robert Galbraith has been such a liberating experience. It has been wonderful to publish without hype or expectation, and pure pleasure to get feedback from publishers and readers under a different name."

In a starement,LB publisher Reagan Athur said a reprint is underway, but it wasn't known Monday morning how large the print run will be. She said LB is also planning to release a second title in the series, which features private detective Cormoran Strike, next year.

PW's starred review for The Cuckoo's Calling calls it "complex," "compelling," and "stellar."
