The Universe is a Hydrogen Sonata

Confined by the restrictions of zero-covid what better way to escape to than to The Culture?

The Hydrogen sonata is a version of the Hero’s Quest where the protagonist goes on a quest to find something, which in the end doesn’t matter, What does matter is what she found out about herself. 

Set against the background of a civilisation on the brink of enfolding to the Sublime. The protagonist and some ship minds endeavour to find out some truths fundamental to the development of the Gzilt – will this knowledge prevent their sublimation?
