I mainly write science fiction and fantasy for children, young adults and adults. My latest series are Twinmaker (sci-fi thriller) and Troubletwisters (with Garth Nix). I live just up the road from the best chocolate factory in Australia.

You might also know my work from Star Wars: I wrote six novels, including the Force Unleashed books. I've also written a bunch of odd poems and a sci-fi musical, just for fun. 

You can follow me on Twitter, Instagram and most places as "adelaidesean", except for Facebook where I'm "seanwilliamsauthor".

This photo of me and my sonic screwdriver was taken by James Braund at Reading Matters in 2015. I'm a massive Doctor Who fan, but who isn't?
