This work of historical fiction flat-out revels in the fact that it is completely made up. This version of the story of Lady Jane Grey, a.k.a. the Nine Day Queen, has the boy King Edward being manipulated and slowly poisoned by his adviser Lord Dudley, Duke of Northumberland. Edward designates his favorite cousin Jane to be his heir and has her married to Dudley’s son Guildford.
So far, similar to reality, but sillier. In this alternate history, some people are Effians, that is having the ability to change into an animal. Swiftly, Jane inherits the throne when Edward is declared dead, and then she and Guildford are forced to flee when Mary in turn claims the throne. Jane, Guildford, and Edward (spoiler: he’s not dead) all have adventures, discover new powers, and meet interesting people along the way to a happier ending than reality. The book is riotously funny both in the dialogue and the authors asides. The audio book is excellently performed by Katherine Kellgren.
