The Idiot King - Ghostspeaker Chronicles

The third book in the saga.

Johanna, Roald, Nellie and Loesie have come to Florisheim finding many of their kinsmen there. The survivors from the burning of Saardam who have come here are the nobles who were never great supporters the old king, and it is likely that they won't support his son either, even if he was normal. They support his marriage to Johanna even less and Johanna's position as the new king's wife would be improved immensely if she produced an heir, but so far that's not happening.

Florisheim is alive with evil magic, and that magic is starting to affect the Saarlanders who are unused to it. They suffer apparitions of ghosts, people driven to injure themselves, or taken prisoner to work in a mysterious hole in the ground.

Johanna knows that they have to get out of that evil place, but where can they go when the violence covers the entire known world?
