I had mixed feelings about this book after reading it. I liked the book because it allows the reader to imagine, but I don't like this book because it's hard to find the message it's trying to convey. The language in the book is clear and simple which allows the reader to finish the book in a paced time. The writing is paced well throughout the book hard to find what the author is conveying. The characters in the story which is Cosmo, his sister, and the robot. The characters are believable and feels as the story is real although its in Mars. As well, the characters in the story are an African American family this portrays multicultural ethnicity in science fiction books. The point of view in this book was in first person the characters had dialogue and tried to find a solution to the evil robot. The illustrations are not too eye catching. I think the illustrations are not very modern to present of 2020 and it might not be eye catching for younger students. Overall, the book pushes readers to think of a solution and to imagine a world outside of earth. I think this book is a very family orientated book and students would enjoy the fantasy out of this world! ( )
