'Coventry House' is a book that can be enjoyed on multiple levels. It works for people who enjoy Tim Powers or C.S. Lewis and Tolkien's more mature works. It works for people who enjoy seeing a different take on various mythologies, ranging from Egyptian to Finnish to Medieval European. And it works for people who like anthropomorphics, or who enjoy reading well-told stories of hope and redemption.
If you like any of that, you will love this story.
As Alice V says, this story feels more like the first chapter of a longer piece which I hope will see the light of day. But it's very well done even as a short, with a colorful setting and characters. There are also some shout outs here and there to other fictional settings that will definitely amuse the readers who get the joke. Very well done story, long enough to entertain without being too long, five stars easy.
