A few days ago I was looking somewhat frantically through the books on the shelves in my closet (yes, I have a floor-to-ceiling bookshelf in my closet) for something to read to my son, Sebastian. Lost Race of Mars almost fell into my lap. I'd read it several times as a child myself, and remembered liking it quite a lot. I'd nearly forgotten about it, but I grabbed it and read it to him.It was written by Robert Silverberg in 1960, and includes some charmingly albeit slightly crude illustrations. Sebastian loved the book, and chuckled over every drawing.It's the story of a family who visits Mars for a year on that far-off date of 1991. The children, Jim and Sally, are the primary focus. But what grabbed Sebastian the most were the cats. First was the family cat, Chipper, who is left behind on Earth early on. Sebastian asked several times if we'd see Chipper again. A few illustrations later in the book showed Chipper, and he was particularly interested in those. He is a cat person (we're a cat family, in fact), so his interest was quite natural. Perhaps someone who doesn't like cats wouldn't enjoy the book as much as we did.There was also Mitten, the Mars cat, in the later chapters. Again, Sebastian loved Mitten and chortled over the drawings of him.The story is nicely paced, well-written, easy to read aloud, and has a very satisfying ending. The science is a little shaky, but not outrageously so (I'm still tempted to look up the temperatures on Mars). The prognostications are way off - a thriving Mars colony by 1991?!? - but that's not an insurmountable problem. The Martians themselves are, well, pedestrian by modern science fiction standards. But they work well for children, and that's who the book is written for. I'll also credit Silverberg with giving Sally, the younger girl in the book, a stronger-than-customary role for the time; she's not simply a stereotypical docile little sister, nor is she one of those cliched "spunky" girls.Sebastian is nine and a half. He's a bit advanced when it comes to books, but I'd say we hit the sweet spot with this one - he's the perfect age to enjoy it. I think any child from say, eight to thirteen would be likely to enjoy the book, and many older children would too.I'm giving the book four stars just because I can't classify it as a deathless classic that will last through the ages. But Sebastian gives it fives stars without reservation.
