Showing The Boggart and the Monster by Susan Cooper

Set in the Highlands of Scotland, The Boggart and the Monster has all the trademarks of a first-class adventure: magic, high-tech expeditions and mythical monsters. The boggart of MacDevon Castle, a mischievous shape-shifting spirit, spends his days happily playing tricks on the new owner of the castle. After discovering his old cousin Nessie miles down in the murky waters of Loch Ness, the boggart must enlist the help of a few human friends to return, with Nessie in tow, to his beloved castle. With a team of scientists hot on their trail, the MacDevon boggart and Nessie begin their adventure. Susan Cooper's inventive writing, infused with both scientific and magical elements, will captivate even the most disbelieving of young adults.
