Mars’ First Friends is a universal story about man’s—and Mars’—best friends: our pets. In this sweet solar system book, Mars is lonely and just wants someone to play with, but the rest of the planets are all too busy. That is, until Earth sends her little brother, Mars, his first pets: the rovers, Spirit and Opportunity! With its darling prose and charming illustrations, this book offers a new take on the Mars rovers stories, and also includes educational back matter with an abundance of information about the solar system, Mars, and the Mars rovers.
