Fifteen-year-old Matt Mitchell was having the worst summer imaginable. His misery started when his mother died in a senseless car accident. Unable to remain in the family's memory-filled seaside cottage, Matt's grieving father moved Matt and his twin sister as far as possible from the ocean they loved.

But their relocation to the small town of Hawthorne, Indiana only made Matt's life more difficult. Three bullies at his new high school dedicated themselves to making him miserable. To top it off, Matt heard that the recluse living in the dilapidated Victorian mansion next door was none other than Old Lady Hawthorne, the town's infamous witch and murderer of wayward husbands.

When Old Lady Hawthorne's niece and her three children moved in next door, something extraordinary happened. Matt met Gerallt, the strange boy destined to become his best friend. And when Gerallt divulged the Hawthorne's family secret, it changed Matt's life forever.

The Secrets of Hawthorne House is the story of an unlikely friendship, the clash of two radically different cultures, secret magic, and a search for the lost Hawthorne treasure.
