The Book of Mice

From the introduction: The aim of this book is to pile together the hay and extend a hand to the struggling mouse, who rarely gets a chance to enter the world motherless anymore. Caves create bears. Rain creates earthworms. Countless sundry mysteries take place in the world every day, just beyond sight and only slightly beyond understanding. The creatures in this book are the product of entirely natural processes, both geologic and environmental. More or less, anyway. User summary: A fantasy bestiary featuring unusual (and generally diminutive) creatures.
