Um dos revisores da Goodreads diz:
I remember reading this as a kid back in the 90s. Although I don't remember much about the plot anymore (except that he saved Earth, of course), I remember enjoying reading this book and giving me a taste of what sci-fi has to offer and for that I always appreciate this book. This is probably out of print now but I was prompted to look up this book here on Goodreads after seeing a picture of two hearts in an alien somewhere on the web because the alien boy has two hearts! I also, for some reason, have never forgotten the last line of this book which is "grass might grow on Gundra (the home planet of the boy)."
E a capa da Amazon se encaixa perfeitamente!
