Ava stumbles upon an old book titled The Silent Sisterhood in a forgotten corner of a dusty bookshop. Inside, she finds a chilling note: “Women who read are dangerous. Keep turning the pages, but beware who’s watching.” As she reads, Ava uncovers clues to a secret society of women who’ve guarded forbidden knowledge for centuries — but now they’re being hunted, murdered one by one. The deeper she digs, the more she feels unseen eyes following her every move. Time is running out. The final code must be unlocked, or the Sisterhood’s secrets — and Ava’s life — will be lost forever.
