Princess Magnolia is stuck having tea with the gray-haired Duchess whose hair is piled on her head like a two-foot tall mini-tornado, when her secret ring goes off warning her that the kingdom is in danger. Not wanting to raise her suspicions, Princess Magnolia comes up with a lame excuse to go change into her black super hero costume and see what is up. In the meantime, a blue monster that lives underground with other monsters is trying to remember why he shouldn't leave his den but he is so hungry that he crawls out anyway. He finds some goats with a shepherd and immediately goes after one. The shepherd named, Duff, thinks the Princess in Black looks familiar and decides to come up with his own superhero costume, Goat Avenger. It would appear that many more adventures are in the making for the Princess in Black and that a sidekick might play a part as book one of a future series ends.
There are quite a few illustrations than one usually finds in this length of book. Or maybe that is because I just finished "Leroy Ninker Saddles Up" and it had noticeably fewer pictures than this one. The color pages add to the fun and gross humor. When blue monster eats a plate of toe-nail clippings I cringed and laughed at the same time. The two-page spread of Princess Magnolia's ninja moves on the blue monster adds to the action and excitement. Duchess Wigtower reminds me a bit of the Disney stepmother in "Cinderella" except her mountainous hair adds humor. A great addition to Mercy Watson series in your library.
