The second book in the Shadow Grail series by the New York Times, USA Today, and Publishers Weekly bestselling authors Mercedes Lackey and Rosemary Edghill
Spirit and her friends Burke, Loch, Muirin, and Addie have managed to defeat the evil force that has been killing students at Oakhurst Academy for the past forty years — or so they think. When a series of magical attacks disrupts the school, Doctor Ambrosius calls upon alumnus Mark Rider to secure the campus — and start training the students for war. The only student without magic, Spirit doesn’t trust Mark or his methods. She knows that Oakhurst isn’t safe. And if Spirit and her friends want to live long enough to graduate, they have to find out what is really going on — before it’s too late.
Rosemary Edghill (born 1956) is an American writer and editor, who has often used that pseudonym in place of her legal name, Eluki bes Shahar. Her primary genres are science fiction and fantasy, but she began by writing Regency romances.
The publishers of her first novel, the Regency Romance Turkish Delight, suggested that "eluki bes shahar" sounded insufficiently English to attract potential readers, and thus she has published the majority of her novel-length works under the pseudonym. Her sister writes as India Edghill.
