What did you get out of it?

I read "His Master's Voice" as a teenager and was deeply touched by it. Every other Lem Book was downhill from then.

The main character being cast into diferent bodies over the course of the story making me contemplate what makes us the person we are and the final monologue at the end, reflecting on whether it is ethical to betray people even if it makes them happier. The value and importance of being honest and true to yourself, even if the truth is hard and hurts.
