How many Russians does it take to write a SF novel?

A few thousand, according to a literary experiment by my fellow writer Andrei Levitsky.

He wrote his recent novel, Invasion. Moscow 2016 (Nashestvie), together with as many fans and beginning writers who co-authored his book online. Andrei posted the work in progress at Russia's biggest writing site, SamIzdat http://samlib.ru , inviting all his readers to offer their suggestions of various story details and its further development.

 This Russia-based Babel-story project proved a complete success. Says Andrei Levitsky:

"You'd think that writing the book itself would be easier, wouldn't you? Quite the opposite. It was exhausting. I had to work to a strict deadline: a week to discuss all the possible plot alternatives with the readers, and another week to actually write it up.  Good job I had a lot of co-authoring experience when there's no way you can let the other writer down or take a sabbatical waiting for inspiration to come.

Working on Invasion proved much harder than I initially expected. For that reason, my next novel, The Anomals , took much longer to write: I needed a break after the Invasion marathon."

Andrei and I have co-authored several books of the TechnoTma series.
