Hunter's moon - Louise Cooper

When Gil and her sister Biddy first spot the ancient church near a deserted beach in Norfolk - and glimpse two silent red-haired children loitering there - Gil never thought that their lives could become so entangled with a terrible curse that haunts the church. Then, inexplicably, Biddy falls suddenly and seriously ill... There is a connection between Gill and Biddy and the strange boy and girl on the beach - they all have identical, flame-red hair - but Gil has no idea why this is significant until she meets her eccentric great uncle, and his daughter Rose, along with Rose's son, Jonas - a red-head, too...

It is Jonas who leads Gil to the heart of the terrifying secret of the red-haired children, and the tortured spirit living in the ancient church who cannot rest in peace. But but uncovering the secret holds terrible danger for Gil and Jonas. Can they face the demon spirit and live to tell the tale?
