in the series, was released on 1 September 2008. In September 2010 Empire of Silver was released, which revolves around the life of Genghis Khan's son, Ogedai. Whilst Iggulden had initially confirmed on his official website that he would be writing two more books after Empire of Silver on Kublai Khan, the author's note at the end of Conqueror states that it would be the last in the series. Iggulden explains his desire to leave the character when he still had much left to accomplish, rather than tracing him through to his eventual downfall, as he did with Julius Caesar and Genghis Khan. Iggulden released a four-book series, the Wars of the Roses series, starting with Stormbird in 2013, Margaret of Anjou (called Trinity in the United Kingdom) in 2014, Bloodline in 2015, and Ravenspur in 2016. In 2017, Iggulden published a historical fiction novel called Dunstan, chronicling the life of the 10th century monk and political adviser to the Saxon Kings of England, St. Dunstan. In 2018, Penguin Books released a historical novel called The Falcon of Sparta, about the effort of Prince Cyrus to become King of Persia and the stranded 10,000 Greek mercenaries who walked out of Persia while pursued by the King's armies following the Battle of Cunaxa. Children's books Iggulden co-wrote a book with his brother Hal, The Dangerous Book for Boys. It covers around eighty topics, from building a soapbox racer and tying knots, to learning about famous battles and how to make potassium aluminium sulphate crystals. It was released in the UK in June 2006, reprinted a month later and was voted British Book of the Year at the Galaxy British Book Awards. In September 2009 he wrote a children's book Tollins: Explosive Tales for Children through HarperCollins. Iggulden has since written three stories to accompany the story of the Tollins. Other works In March 2006, Iggulden released a novelette entitled Blackwater, part of the Quick Reads initiative of World Book Day 2006. Being a thriller, Blackwater was a change in genre for Iggulden who had mainly written historical fiction. In 2012 Iggulden added a further quickreads book to the list Quantum of Tweed – The Man with a Nissan Micra – a comedy about an unwitting hitman. Fantasy novels In 2017, Conn Iggulden released the first book in his first fiction fantasy series, Darien: Empire of Salt. This series is being published
