Hidden among us is a secret government department of witches known as Her Majesty's Royal Coven. They protect crown and country from magical forces and otherworldly evil, but their greatest enemy will come from within. There are whisperings of a prophecy that will bring the coven to its knees, and four best friends are about to be caught at the centre. Life as a modern witch was never simple... but now it's about to get apocalyptic. The Sunday Times number 1 bestseller and spellbinding start to a new fantasy series.
