Dan Brown's book The Lost Symbol has set a weekly UK sales record for a paperback novel.
The follow-up to The Da Vinci Code sold more than 140,000 copies in its first week, setting a new benchmark according to industry magazine The Bookseller.
Brown's latest novel beat the record set by its predecessor in 2005, adding on some 16,000 sales.
The Lost Symbol topped the Christmas book charts ahead of the 2010 Guinness World of Records.
When the hardback edition hit the bookshelves in September, it sold more than any other hardback in its first 36 hours on sale.
US novelist Brown has sold £78.5m worth of books since the publication of Angels and Demons in 2001, added The Bookseller.
It went on to say that sales of books are buoyant at the present time due to offers in retailers including Waterstones and WH Smith.
Also this week, the highest new entry on the book chart was Katie Price's novel Sapphire, landing at 24 with sales of nearly 11,000.
