"Sing, and the darkness will find you." This warning has haunted fifteen-year-old Lucy since she was shipwrecked on an island at the age of eight. Lucy's guardian, Norrie, set many rules, but the most important was that Lucy should never sing. Never. In 1667, on All Hallows' Eve, Lucy hears the alluring melody of the wind. She involuntarily sings, and darkness envelops her. Waking up in England, Lucy hears a conversation about Singers - women who can cast magic through songs. She is hunted, but escapes and takes refuge in the Unseen College, an organization that intends to overthrow the Lord Protector. But only the Singers can do this. And Lucy is the last Songster in England. Lucy is trying to learn spell songs and control the power, but the Lord Protector does not sit still. And her feelings for Nat, a student of the Unseen College and a scientist who does not believe in magic, only increase her confusion... Time is short, and the fate of England hangs in the balance.
