Arcade and Daffodil are twin sisters born one minute apart. With their fiery red hair and thirst for an escape, they form an unbreakable bond nurtured by their grandmother’s stories. Together they disappear into their imagination and forge a world where a patch of grass reveals an archaeologist’s dig, the smoke emerging from the local paper mill becomes the dust rising from wild horses galloping deep beneath the earth, and an abandoned 1950s convertible transforms into a time machine that can take them anywhere. But no matter how hard they try, they can’t escape the generational ghosts that haunt their family. Years later, a local woman is discovered dead in the river. Soon, more bodies are left floating in the water, and as the killer circles ever closer, Arc’s promise to keep herself and her sister safe becomes increasingly desperate – and the powerful riptide of the savage side more difficult to survive.
