Olly and Beverley have set their heart on a move to a peaceful and tranquil setting following all of the upheavals in their home town of Becclesfield. They soon move onto a small island three miles off the mainland of Paganton. It appears to be their dream home and the neighbours are so friendly. As the weeks go by, Olly sees a change in his wife's demeanour and attitude. She has become distant towards him but appears closer to all of the neighbours? In time everything becomes obvious to him and he has found an ally in Katie. Together they search for the only thing that will help them get off the island, The Book of Shadows. It becomes a race against time as all the other islanders belong to a secret cult and Olly is their intended sacrifice on The Day of Wrath. Olly and Katie have discovered a number of underground tunnels and many of the island's secrets are revealed to them as they desperately search for The Book of Shadows.
