"I purchased this book with the intention of giving it to a child, but of course, I always read these books first to see if my gift choice is appropriate. I was not disappointed with Ms. Nation's story about Frederick the Cat who made it to Mars. The story is told from the perspective of the cat, yet it still a quite human experience. The language is age appropriate for primary school readers, yet the plot is entertaining for teens and adults to read." - P.O.
