This might be the great book ever written. Maybe.I can best describe this book as "written by a committee of 6-year-old boys with impeccable rhythm." It's got diggers and backhoes and cranes and sound effects and ten different dinosaurs building something very special. I won't spoil the surprise ending for you, but it's pretty cool what ten dinosaurs can build in ten pages.The rhythm and cadence of this book are great, makes for a fun read before bedtime. I don't even mind reading it five times in a row, as is usually requested. My daughter loves to count the dinosaurs and say the sound effects with me. The only downside is that she is disappointed when she sees a backhoe in the real world and it is not being manned by a T-Rex.
