Books that are like “the good place” in the sense that they have fun quirky characters exploring philosophical concepts and twists in a fantasy context. And most importantly the hope and positive message.

I'm looking for a book to read after finishing this show. Realize that I'm really going to miss the sense of hope and optimism against adversity.
And the philosophical nature of that hope and adversity. And the exploration of a fantasy world through all of that that is directly tied to those themes.
