It's a sci-fi story where this guy travels to different worlds and saves them.. allAll I specifically remember is that on each world he goes to, the people had differentdifferently shaped ears.. (Iears; I think in the last book I read, they had square ears..) by By the 4thfourth book, the story was getting a bit redundant, but I still wanted to find out how things turned out..
I remember the title of the last book I read was BLANK's Opal.. just'BLANK's Opal' (just gotta fill in the blank.). itIt was a name that began with an O... Anyone know what I'm referring to? TIA! 🙂🙂
