Disquiet (Strugatsky novel)

Disquiet (Беспокойство) is a 1965 sci-fi novel by Boris and Arkady Strugatsky set in the Noon Universe. It is the initial variant of the novel Snail on the Slope (Улитка на склоне) which has a different set of characters and is not set in the Noon Universe. After completing the first draft, the authors felt a need to take the novel in a different direction, which resulted in the creation of Snail on the Slope. However, twenty-five years later, they examined the initial draft and concluded that it was a decent novel in its own right. In 1990, it was published in Dimension F magazine. In 1995, feeling the need to expose it to the wider readership, Boris Strugastky published it online.
