The Story So Far
Anthony Monday is delighted when Miss Eells and her brother Emerson invite him to spend a restful summer vacation in an old house on a desolate island. But soon Anthony finds a chest that can transport them to another world -- a horrifying place where a maniacal group is plotting the destruction of the people of Earth. Will Anthony and his friends be able to save mankind -- or will they perish in their desperate struggle?
The Mansion in the Mist (1992), by John Bellairs, is the fourth book in the Anthony Monday series.
