The Vanishing Volume — Marissa Doyle

Young widow Annabel Chalfont, Countess of Fellbridge, has two small sons to raise, a mountain of her late husband's debts to pay off, and a secret: she's a shadow-shaper, able to manipulate shadow as anyone else might clay. She and six other high-born ladies with equally extraordinary abilities defend England against supernatural crime--but the world knows them only as the Lady Patronesses of Almack's, Regency London's most exclusive social venue.In the second installment of The Ladies of Almack's series, all of London is enthralled by E.C. Spruce's latest three-volume novel, The Fifty Shades of Udolpho...until the third volume begins vanishing from bookshops and bedside tables alike, leaving readers dangling and desperate to know what happens next. The Lady Patronesses of Almack's investigate, with unexpected results--and an unexpected new friendship for Annabel...or perhaps two friendships, if she'll only admit it...
