The eBooks, available in Epub, Mobi (Kindle) and PDF versions, are just part of the premium content available in the members area of the Sofanauts website. Since launching in early 2014 with a monthly subscription fee of £6 (around $10 US), this has also included lectures by science fiction legends like Harry Turtledove, interviews with authors such as Gareth L. Powell, and three previously published science fiction short story anthologies by StarShipSofa.
The first eBook in the series is the 2011 story FarmEarth, by Paul Di Filippo, a near-future tale of brain enhancements and the gamification of environmental management in a world affected by centuries of industrialisation and ecological collapse. It features a specially commissioned cover by artist Scott Pellico.
Look out for further eBooks in the months to come!
