What was the UK's best selling book of the 2000's (2000-2009)?

You will not be surprised to learn that one author dominated the book industry in the 2000's - but the extent of JK Rowling's success may still take your breath away.

The seven Harry Potter novels sold 27.6 million copies over the last 10 years. That is more than double Rowling's nearest rival, Dan Brown. However, despite that, Brown snatched the honour for biggest-selling book of the decade from under Rowling's nose with the "Da Vinci Code".

The rip-roaring, church-bothering thriller, sold a staggering 5.2m copies in the UK, far more than the most popular Potter novel, "The Deathly Hallows", on 4.37m.

Both Rowling and Brown exemplified a noughties phenomenon in literature, whereby the boundaries between adult and children's books slowly blurred. It was not uncommon to see adults clasping the latest Harry Potter on the bus into work - but children were equally at home reading Mark Haddon's Whitbread-winning mystery novel "The Curious Incident of the Dog in the Night-Time".

"The Life Of Pi" was the biggest-selling Booker Prize-winner of the decade. The era of the "blockbuster" 1,500+ page novel seemed to have come to a sudden halt, with portable fables like "The Life Of Pi" and "The No. 1 Ladies Detective Agency" the handbag books of the decade.
