@ricci@discuss.systems I think Dennis E. Taylor's #Bobiverse series might be worth a mention here for being both (relatively hard) #SF along with making really light reading because of the abundance of references to and gags involving other SF works. Andy Weir's Project Hail Mary might also tick your boxes and it has great production value. It also won an Audie if that means anything to you. Incidentally, Ray Porter is the narrator in all of the above cases.
