Another complete book of Celtic capers and Welsh witchy wonder brimming with cats, magic, mystery and … scarecrows. It’s an exciting summer in the small town of Llanfair. There’s a scarecrow festival and Maddie’s mother, Ceri, has come to revisit the place where she grew up. Except there was a reason she left for America all those years ago, and that reason hasn’t gone away. Well, not exactly. It has changed, however, and gone underground. Literally. Now a dark secret lurks in a Neolithic barrow and Ceri’s arrival has sparked its awakening. Someone is in danger. It’s not clear who that is. Meanwhile, Mad Aunt Dilys has created a scarecrow that might get her arrested, Gruffydd is getting more enigmatic by the day, curse poles are popping up, and Bron herself indulges in a little light arson. It’s mostly accidental. But totally life-changing. All good people do bad things sometimes. How many bad things can you do before you’re not a good person any longer?
