In this very entertaining book and using spare language, Voake uses a childhood favorite for demonstrating the concept of size and proportion, and teaches readers a little about dinosaurs to boot. The story opens with a very small green dinosaur filling a pill up with fruits to eat later, while nearby lurks a very large dinosaur watching the little one. And yes, you guessed it, the big dinos gang up on the little one and take all his pickings to eat themselves. But is this the end of the story? No indeed it isn't, because size is relative and in this case, it's relative to the age of the dinosaur. And young readers will definitely laugh when they discover that little one's mom is enormous, relative to the large dinos. This is a great book for preschool and beginning readers. The text is simple and large, the unexpected ending is done with age appropriated humor and the quirky, but very appealing watercolor and ink illustrations, done is dusty shades of brown, green, and red, give the story a very prehistoric sense. I read this (repeatedly) to my young readers who loved it, a few of whom are budding dinosaur fans, and I'm pretty sure we will be reading it again and again.
