The latest Diary of a Wimpy Kid novel has become the fastest-selling novel of 2011 so far, according to new figures.
Cabin Fever, the sixth book in the series by US author Jeff Kinney, sold 81,656 copies in its first four days.
Kinney’s previous weekly sales personal best was 30,312, set by fifth book The Ugly Truth, in November last year.
Cabin Fever follows middle school child Greg Heffley as he attempts to fit in at school and deal with his brothers Manny and Rodrick.
It is publisher Puffin’s biggest weekly sale since BookScan records began in 1998, while the book’s 500,000-copy initial print run is the largest in the publisher’s history.
