Rae ran away from his home; then he ran away from his world. Now, 400 years later, he is told he must return, and claim what he was running from: the throne.
Rea returns to his home world with Jon and Jym who left with him when they were all sixteen years old. Now they begin the process of making him king.
Rae, Jym, and Jon discover something only the Thorns suspected. There is an entity living under the throne room. It controls the secret power plants that are on the world.
These power plants are now in disarray from lack of use and from being shut down centuries earlier.
Additionally, once he has become king, he must unite the other countries and stop the plague that is killing the people of his world. Will he accomplish this, or will he fail like all the kings before him?
