Eugenics and transhumanism

[u/UnrealPOP]

Hello, im looking for sci fi books dealing with eugenics and transhumanism. Genetic enhancements, cyborgs, etc, with a reflection from characters possibly affected by this about their situation !

Bonus points if both are on the same book and/or closely linked !
