What happens when you find yourself turning into the thing you despise? Becoming a sprite has come with the consequence of learning how to be tricky, a trait Nathanial has never respected but now relies on for his survival. He must use this skill to navigate the castle walls in which young sprites are learning how to properly dominate the planet. Having come here to free Aliya, Nathanial must now save her from a fate worse than her imprisonment, but she may not be the only one in need of a rescue. A voice is calling to him from within the diamond veins of the volcanic walls, and if he isn't careful, Nathanial could find himself trapped within the diamond forever. Join Nathanial on this third exciting book in the Nathanial Thatcher Series
