"What most small boys would agree is the perfect book...And the art is just plain beautiful"
—The Washington Post

*"An action-packed science-fiction romp starring a cast of dinosaur characters…This story blends eye-catching layout with a quick-moving plot, tongue-in-cheek humor, and an imaginative setting. The dinosaurs, who wear funky-looking space gear and have an endless supply of gadgets, are a blast… Sci-fi fans and dinophiles will eat this book up, and it might also capture the interest of reluctant readers."
—School Library Journal (starred review)
