Just ended with 'Children of Time' by Adrian Tchaikovsky and will now start 'Children of Ruin' (the second in the series). I liked it a lot,... the gist of it:
Humans terraform planets
Humans want 'crispr' intelligent apes
Humans kill each other
Crispr can't find apes,.. uses spiders instead
Other Humans come eons later and find intelligent spiders
The story is told through the eyes of the spiders and the surviving humans and how they try to communicate, think in different terms, fight for the last habitable planet,....
