EL James's sequel to 'Fifty Shades' series, 'Grey' has sold over 1.1 million copies within a week of its release in the US, breaking adult book sales record.
The book, which retells the erotic story from the lead Christian Grey's point of view, has become a hit despite facing criticism, the Guardian has reported.
The 52-year-old British author James has mentioned in her dedication that fans had "asked . and asked . and asked . and asked" for the SandM businessman's perspective.
The record for a first-week sale for an adult title is currently held by Dan Brown's 'The Lost Symbol,' which was published in October 2009 and had sold 551,000 copies in its first week.
