Rather than focusing on more general myths and legends, [this] series offers a peek into specific monsters and mythical beasts as they appear in world mythologies. By necessity, each of the books is somewhat brief, rather than delving into any topic in depth. Unicorns is the best of the set, narrowing its focus primarily on the Medieval romantic unicorn, providing small anecdotes about earlier appearances of unicornlike creatures in mythology, and leading into modern depictions of unicorns in popular fiction. Bigfoot and Yeti and Werewolves do an excellent job with their subject material. . .
