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.
Mercedes Ritchie Lackey (born 1950) is an American writer of fantasy novels. Many of her novels and trilogies are interlinked and set in the world of Velgarth, mostly in and around the country of Valdemar. Her Valdemar novels form a complex tapestry of interaction between human and non-human protagonists with many different cultures and social mores.
Her other main world is one much like our own, but it includes clandestine populations of elves, mages, vampires, and other mythical beings. The Bedlam's Bard books describe a young man with the power to work magic through music; the SERRAted Edge books are about racecar driving elves; and the Diana Tregarde thrillers center on a Wiccan who combats evil.
