In a few short days, South Bundelag will invade the North with their entire human army. While the fairies, elves and ogres prepare their defenses, Arica and Connor travel to troll country at the fairy queen's request to convince the trolls to help them. But their leader refuses. So do the dragons. On the eve of the invasion, Connor finds a prophesy in the *Book of Fairies* that convinces Arica she may be able to use her magic, and that of the unicorns, to move forward to victory.
