One Day sells 60,000 copies in seven

David Nicholls' One Day (Hodder), the adaptation of which hits cinemas later this week, was comfortably the bestselling book at UK booksellers last week.

The novel, first published in 2009, sold 60,410 copies across all printed editions at UK booksellers last week, outselling the next most popular book, Lee Child's Worth Dying For (Bantam) by more than two copies to one.

The original February 2010-published mass-market edition tops The Bookseller's Official UK Top 50 this week with a 32,357 seven-day sale, while the new film tie-in edition takes second place on a sale of 27,780. It is the first time two editions of the same book have topped the charts since August 2007 when the adult and children's editions of J K Rowling's Harry Potter and the Deathly Hallows (Bloomsbury) took positions one and two in the charts.

It is the third time One Day has topped The Bookseller's Mass-market Fiction bestseller list, having crowned the chart in February and December last year. Linwood Barclay's No Time for Goodbye (Orion), in the summer of 2008, was the last novel to regain the top spot in the charts for a third time. Hodder publishing director Nick Sayers said the book sold more than 12,000 copies in e-book format last week.

Sales of the novel, which were up 45% week-on-week, were helped by a spot in O2's "Priority Moments" promotion, which offers O2 customers selected novels for half price at W H Smith. Another member of the promotion last week, Paul O'Grady's The Devil Rides Out (Bantam), saw its sales jump by 26% week-on-week.

New entries into the Official UK Top 50 include James Patterson and Liza Marklund's Postcard Killers (Arrow), a half-price "book of the week" at W H Smith, Erica James' Promises, Promises (Orion), a "£2.99 with the Times" deal at the same retailer, and Madeleine Wickham's latest backlist novel to undergo a jacket revamp, Swimming Pool Sunday (Black Swan).

Thanks to a better-than-half-price "deal of the week" at Amazon.co.uk and a spot in Waterstone's half-price "for one week only" promotion, Mark Billingham has scored his first ever number one. His 10th DI Tom Thorne thriller, Good as Dead (Sphere), was the bestselling hardback fiction book of the week. It narrowly beat Peter Robinson's standalone thriller, Before the Poison (Hodder) to the number one spot. Billingham's novel sold 5,383 copies, just 66 more than Robinson's.

The Language of Flowers (Macmillan), Vanessa Diffenbaugh's début novel that was subject to a nine-publisher auction, also débuts in the Top 20 Original Fiction chart thanks to an opening-week sale of 1,766 copies.

TV chef Simon Hopkinson scores his first ever number one this week, his The Good Cook (BBC) hitting the top of this week's Top 20 Hardback Non-fiction list. Rick Stein's Spain (also BBC) falls one place to second position while tennis star Rafael Nadal's Rafa: My Story (Sphere), is this week's highest new entry at number eight.

Bill Bryson's At Home (Black Swan) stays firm at the summit of the Top 20 Paperback Non-fiction chart week-on-week, clocking up an 11th week at the top. Only two books have bettered this in the past three years: Elizabeth Gilbert with Eat, Pray Love (Bloomsbury) and Barack Obama with his Dreams From My Father (Canongate).

Jeff Kinney's Rodrick Rules (Puffin), book two in the US author's Diary of a Wimpy Kid series, was the bestselling children's book last week, scoring sales of 4,680 copies. Kinney has been worth more than £6m to UK booksellers thus far in 2011.

In total, £26.2m was spent at UK booksellers last week, down 2.3% on the previous week and down 7.2% on the comparative week last year. As has been the case all summer, spending on novels was well behind last year as the digital sector continues to cut into printed book sales.
