If you want Astonishingly Amazingly Beautiful in a children's book, look no further than the writing/illustrating team of Dianna Hutts Aston and Sylvia Long. A Rock is Lively is Aston and Long's fourth joint effort following the success of An Egg is Quiet, A Seed is Sleepy, and A Butterfly is Patient. I knew this would be a lovely book, but I'd almost despaired of obtaining a copy in time to evaluate it for the Cybils when my librarian friend surprised me with the book last week. I hope you'll forgive me for loving this book best of the series as my husband is a longtime rockhound and gem cutter. I've seen a lot of beautiful rocks and a lot of beautiful rock books, but I must say that I've never seen more beautiful rocks in a more beautiful rock book. And not only is it beautiful, but it explains rocks better than any other rock book for children that I've read.Fabulous. It will not disappoint.
