After the somewhat standalone narrative of The Secret Throne, Taggie and Jemima are back in England. After a series of assassination attempts against royals, they must face a threat not only to the First Realm, but to all the realms. The adventure takes them to the occupied Fourth Realm, where winter and evil reign.
The second book in the series is more complex and more exciting than the first, as if Mr. Hamilton is becoming more comfortable with the fantasy medium. The story is both engaging and thought provoking, as characters of supposed integrity find their beliefs and ethics challenged when confronted with adversity.
