Ronan Lynch, one of the "raven boys" from Aglionby Academy, can take things out of his dreams and into waking life. This power could prove useful in the raven boys' search for the burial site of a dead Welsh king named Glendower, who they think sailed to America a long time ago. However, now that Ronan's secret power is being used more often, a dark enemy had learned about it, and plans to use it for his own gain.
