Lady Lyssica Aphiski, unexpected heir to the Duke of Papillion, is driven to prove to her father she is capable of fulfilling her role - even if it means juggling her estate duties with her secret and sacred responsibility as hand-maiden to the Unseelie Goddess, Ostara. Everything is going swimmingly until the first snow of winter arrives weeks ahead of schedule. If that wasn't enough, the participants for the Tri-moon training program arrive, bringing with them a terror from Lyssica's past. When Lord Emryn Phengaris agreed to represent his Changeling Clan in the Tri-moon program, he had no idea he'd end up as personal bodyguard to the gorgeous Lady Lyssica Aphiski. To make matters worse, his animal side insists she's their mate, which is impossible because, despite his fascination with her steel spine and shimmering smile, she's not changeling. Then a Tri-moon apprentice is murdered by an ancient evil determined to bring about eternal winter. Only one thing stands in his way - the magic Lyssica has kept secret since childhood. With her world thrown into chaos and danger at every turn, Emryn proves the anchor Lyssica never knew she needed. Together, they must find the strength to vanquish not only the demons threatening the Queendom, but the ones inside their hearts.
