The adventures in Cry at Midnight – Book One of The Hagstone Chronicles have ended. The Witch of Tiree is dead and Kester, the young wizard has returned to his people. Hamish has forgotten everything that happened, but Merryn will always remember. The necklace of sea-beans and hag-stones has hung unmoving round her neck. Now, on their first day on the Isle of Kerrera, it begins to throb – a sure sign that there is malevolent magic in the air. Merryn warns The Benevolent Wizards; but trying to defeat the evil witch, Ammonia B Clickfinger, leads them all into even greater danger.
