This is the final gripping instalment in the twisting series that will have fans of 'One of Us is Lying' and 'Pretty Littles Liars' hooked. Determined to crush the Order of the Stag once and for all, and in a desperate last throw of the dice, Greer walks willingly into the lion's den by accepting a sinister invitation to Castle McLeod, a Scottish stately home in the Isle of Skye. Greer will be aided and kept safe by Shafeen and Nel, and the enigmatic Abbot Ridley. Plus, of course, Henry de Warlencourt who will accompany her and insists he has changed his colours. But as their darkly fraught romance evolves, can Greer trust him as she places her life in his hands?
