Solaris by Stanislaw Lem. A psychologist is sent to a station in orbit around a planet covered by a sentient ocean to determine if research on it should continue. Lem's work consistently blows my mind, actually--other favorites are His Master's Voice (memoirs of a mathematician working on a project to decipher what might be a message from extraterrestrials) and Peace on Earth (an adventurer returns from a trip to the moon with his brain bisected, and the half that remembers what happened is both unable and unwilling to communicate it).

The main cast of Eternal Punishment is adults, and although it suffers from making Maya a silent protagonist when she was such a dynamic character in Innocent Sin, the themes of self-discovery remain very much intact. As a follow-up to Innocent Sin, where high schoolers make heavy sacrifices for the sake of the world, Eternal Punishment shifts the perspective to adults who think, "those are just kids, they shouldn't have to deal with this."

The idea that Asimov's laws of robotics are an actual set of guidelines for building robots is laughable
