Actual Size, etc.) are among my very favorite non-fiction books for kids. That said, this book is about earthworms....not the most thrilling or glamorous of earth's creatures. Sure, they're super important ecologically speaking and we got a good giggle thinking about how they essentially build their doorways out of poo. But, honestly, an earthworm is a super simple, spineless creature with no eyes, no nose, no ears and a rear end that's barely discernible from it's face. It's hard to make that thrilling on a visual level, but Jenkins does his level best. Recommended for those specifically studying bugs, invertebrates or earthworms, but don't expect a thrill a minute read.
