Molly doesn't understand why real life can't be how it is in books. In books, mysteries are solved, questions are answered and parents thought to be dead always come back. Sadly, in Molly's case, this doesn't happen. Molly and her sister Hannah have lost their mother. Since she passed away, their father cannot care for them, so he sends them to live with their grandparents in another town.
Hannah absolutely hates living with her grandparents and desperately wants to run away. She convinces Molly to go with her on a stormy night. When Molly loses track of Hannah, she gets lost in the woods and runs into a man who is being hunted! The man barely survives, but tells Molly to go home before she can find out any information about him.
The next day, Molly and her classmates go on a field trip to a local church. While on the trip, Molly sees a man made of stone and realizes that he is the hunted man from the night before. But this is impossible! The man she saw the night before was very much alive and this man is made of stone. Molly asks her teacher about the man made of stone and she learns that he is known as The Green Man. Rumor has it that he used to be the god of spring or summer, and that he is somehow connected to death and rebirth.
Molly and her sister both want to return to their old house and live with their father. If their mother were still alive, they could return to being a part of a happy, normal family. Could this man bring her mother back to life?
