Maya is a young woman with a checkered past working as a speech therapist at a psychiatric hospital. When a young man, Lucas, suddenly appears after living off the grid with his father in the Minnesota Boundary Waters, Maya is forced to take him on as a patient. As she tries to coax any form of communication from him, she begins to wonder if he has more of a connection to her past than either realizes. I'm not sure I would characterize this so much as a thriller but instead as a psychological mystery. The action is actually pretty slow but has such an interesting plot, that the pages turn really fast. I especially enjoyed the beautifully atmospheric descriptions of the Boundary Waters and am more than ready for a trip up North. I received a physical ARC of this book from the BookishFirst program in exchange for an honest review.
