Sadly Amazon shut down Kindleworlds in July 2018 and all the works I had were lost. Maybe someday I’ll collect them somewhere (maybe even this site) and finish the March of Cobra but for now it remains unfinished.

Kindle Worlds was a service set up by Amazon that allowed creators of different properties to open those properties up to unofficial stories written by fans and authors. Hasbro put G.I. Joe up on the site soon after it was launched. The books published were available for sale and the authors got royalties.
See the drop-down menus for more information on the various stories I had written.
