After a gap of six years, Sebastian Faulks was commissioned by Ian Fleming Publications to write a new Bond novel, which was released on 28 May 2008, the 100th anniversary of Fleming's birth.  The book—titled Devil May Care—was published in the UK by Penguin Books and by Doubleday in the US.  American writer Jeffery Deaver was then commissioned by Ian Fleming Publications to produce Carte Blanche, which was published on 26 May 2011.  The book updated Bond into a post-9/11 agent, independent of MI5 or MI6.  On 26 September 2013, Solo by William Boyd, set in 1969, was published.  In October 2014, it was announced that Anthony Horowitz was to write a Bond continuation novel.  Set in the 1950s two weeks after the events of Goldfinger, it contains material written, but previously unreleased, by Fleming. Trigger Mortis was released on 8 September 2015.  Horowitz's second Bond novel, Forever and a Day, tells the origin story of Bond as a 00 agent prior to the events of Casino Royale. The novel, also based on unpublished material from Fleming, was released on 31 May 2018.
