In an alternate Britain where witchcraft is real - and punishable by death - a note at Larwood House boarding school sparks chaos: 'Someone in this class is a witch.' As suspicion falls on the outcast students Nan Pilgrim and Charles Morgan, they begin to realise they truly are witches, and their powers spiral out of control. With the threat of an Inquisitor closing in, they and a few others flee, seeking help from a secret network. Their quest leads them to summon the enchanter Chrestomanci, who reveals that their world diverged from ours and that they must undo history to save themselves, even if it means losing their magic forever. Witch Week by Diana Wynne Jones is a captivating tale of identity, bravery, and the perils of power.​
