"LIKE SINKING INTO QUICKSAND, THIS NOVEL IS DELIGHTFULLY INESCAPABLE." Four friends discover that the house swap holiday they thought they booked in the beautiful seaside town of Barton-on-Sea is actually in an entirely different place, also named Barton; a seedy, corrupt slum filled with dark and crooked inhabitants. They decide to stay one night to try it out but one night is more than enough to begin their grisly transformations, as each of the friends changes into one of the people who live there. This isn't the end as they find their minds shifting too, to match their new identities. It becomes a race against time as the four friends struggle to reverse the changes that have occurred before it's too late. Before they lose themselves completely. Something strange is going on in Barton but the more they investigate the closer they come to realising that the secret of their dark transformations may be too big for them to conquer. There may be no way back. "A REALLY UNEXPECTED ENDING"
