"Rocks are universal--they can be found in all climates, countries, and communities--making themselves available to anyone who craves the tactile pleasure of holding a perfectly sized, unfragile, unowned object. They can be collected, compared, stacked, plunked into water, painted, and shared. This book is an appreciation of their versatility and appeal, paired with the presentation of real types of rocks and their play-worthy attributes. The back matter provides just enough extra information about each of the rocks included in the book"--
