Cryptids, Creatures & Critters: A Manual of Monsters and Mythos from Around the World features 90 different creatures from around the world, each with their own researched description and full-color illustrations. The book is divided into three sections: cryptids, folklore, and mythology. It features popular cryptid favorites, such as Mothman and the Flatwoods Monster, and some lesser-known cryptids, such as the Enfield Horror and the Montauk Monster. For folklore, there are kelpies, selkies, cat sidhes, and grimalkins, along with the dobarchu and the vampiric pumpkin! In mythology, you'll find Medusa, sphinx, Pegasus, and the bukavac!

The book is fun for newcomers to cryptozoology, folklore, and mythology but is also fun for those who are well read about the creatures in the book. While written by Rachel Quinney and mainly illustrated by her, there are twelve guest artists featured within the book, too.
