The Tyro by Carol Holland March
Larreta, home of the dreamwalkers, is being torn apart.
Rifts are forming and swallowing everything in their path. People, structures, entire villages, are disappearing. No one knows where the rifts come from or how to stop them. And they are getting worse.
Leo, a Senior Dreamwalker, is recalled from Earth, where he fled rather than face his failures. His heightened ability to connect with the past is crucial to combat the rifts. He’s drafted to train a handsome new dreamwalker, Jesse: a young man whose own talents are part of the solution to stopping the destruction.
Together, the two must form a complicated passage through time and space, and they can only succeed with mutual trust. First, Leo needs to overcome his personal demons in order to make the necessary connection. But getting closer is not something he wants to do, in spite of his attraction to Jesse. However, the fate of more than one world rests on their success. And time is running out.
