The Lost Prince by Sara York

Danger lurks in the forests, but will he know to hide?

Crave Woods hides his truth from everyone, even the couple who raised him or tries to. But his family knows he didn’t outgrow the strange affliction of being able to sink into the dirt and travel below ground.
Devin Dumtsteed can’t quit his job though he hates it. If only he had better powers, he could do more for Abarra, but he tracks criminals and illegal power users, getting them off the street before they do something stupid, like kill someone.
A freak cave-in at the mine has him traveling to a small town to check out the undocumented power users when all hell breaks loose. Is the unassuming young man he met in the middle of the forest the cause of the cave-ins or is Crave Woods more than Devin could ever imagine?
