This is book 3 in the Nathaniel Fludd Beastologist series, of which I am a big fan.  Each book in the series focuses on a mythical beast, this time a Wyvern.  In this story, Nate heads off to Wales to solve a new mystery and restore peace to the land.  Written with humor and edge-of-your seat adventure, these little treasures are fun as read-alouds or for the silent reader.  Our elementary readers enjoy tracking Nate’s progress toward becoming a confident and competent Beastologist.  Boys and girls tend to enjoy this series equally.  The illustrations add interest and depth to the story and help to keep the reader engaged.  I highly recommend this book and series for an elementary audience.
