Sarah Martin isn't the only outsider in her small Muskoka town. But when she's teamed up with Byron Hopper for a geometry project, she discovers that she's had an easier time being accepted in her new town than some long-time residents.

Byron's family has long been the subject of rumours. Some say that they are a mob family, some say they are part of a witness relocation program, some say they are just plain weird. But the most sinister rumour surrounds Byron's sister, Garnet, who many believed committed murder.

Sarah resolves to get closer to Byron to find out more about his family ... and get to the bottom of the alleged murder. In so doing, she learns that the family has another secret: they're Wiccans. As Sarah learns more about the family, she also cuts through popular misconceptions about Wicca and finds out what Wiccans believe, how they worship, and what values they hold dear.

Peer pressure and town gossip are two issues that Caroline Pattison deals with in this insightful and compelling tale about fitting in.

The Law of Three made me see something that I always knew, but never really understood. Caroline Rennie Pattison wrote a mystery novel, but layered beneath the folds of suspects and crime, she hid bits of lessons. She taught me that rumours all start with a misunderstanding, and don't just hurt, but can also ruin the lives of an entire family.
