For keep the brain working and sci-fi I recommend you "EVO - Padres" by Ignacio Fernandez Moreno, spanish only but easy to read with B2 level or upper. It's a science fiction novel exploring politics based in evolution in a far away planet.
Can you provide a link to this book? It sounds right up my alley but when I search on multiple search engines and book dBs I’m not seeing it anywhere or even references to it. Ai not finding it either
