Her Majesty's Royal Coven by Juno Dawson

A secret government coven of witches is shaken when a prophesied, dangerously powerful teenager emerges, forcing four former childhood friends—now a high priestess, a healer, an activist, and a suburban mom—to reckon with their divergent beliefs. As they navigate state power, prejudice, and the ethics of protecting versus controlling magic, old loyalties splinter into political intrigue and personal betrayal, culminating in a shocking twist that imperils both their sisterhood and the future of the magical world.
