The Hydrogen Sonata

Story: As advertised we have a space fantasy that also has a mystery “finding a lost thing” trope going and that works well.
Character: All the mains are interesting in their own ways and own reasons. No real classic villains more that folks are at odds. Both have valid points.
Setting:Space, post scarcity utopia that is The Culture. Always enjoy visiting that world.
Language: Funny, silly, angry and well Banks.

I enjoyed it but I think it is too long. Don't know if editing was needed or Banks just had a lot say? But that does drag it down a bit.
