I’ve only read speaker for the dead

I was acquainted with Ender’s character because I watched the movie. Like the storyline and was intrigued by its ending. Read Speaker a few months ago. Absolutely loved it. Became one of my favorite books. I now can’t think I’m even going to enjoy Enders game after such a massive and amazing story as speaker is. Which book would you recommend I continue my journey into Enders saga with? And why? No spoilers please
