A second novel from the bestselling author of Branford Boase-shortlisted and Carnegie-nominated Witch. An engrossing story of fathers and sons, death and grief, and unexpected bonds, new and old, forged by dark and benign magic. When Sam, grieving the death of his father, finds a silver-flecked stone, ice-cold to the touch, strange and eerie things begin to happen. Myth, legend, magic and witchcraft mingle on the ancient hillside where the chalk white horse has galloped for centuries. Ravens wheel. Wolves prowl. As Halloween draws close, witches dance. Odin gathers brave, fallen warriors to his side. Only the mysterious new girl, Oona, can heal Sam's heart, revealing tarot secrets with her bewitching ways.
