When Emma Brodie, local prophet and mother of three, steals a boat and exiles herself to the middle of the bay for seven days and seven nights, she sets about a chain of strange events in the sleepy village of Garfax – a village no longer listed on any official government document. Radios begin to speak secrets, a rainstorm occurs that lasts for months, a young boy dies mysteriously after following the dictates of his heart, and Caleb Anson, the village's prodigal son, returns after a long absence with a grand design to bring Garfax into "the future." This magic realist tale, where dead relatives play dominoes in the houses of their loved ones, is told by Emma's youngest son, Oswald, a shy, observant boy living in the shadow of his charismatic famiy. Wonderfull tells the stories of Garfax – which has become a legend to outsiders – and reveals how this village's unlikely past catches up to its inevitable future.
