Once there, she is confused when she experiences sensations of déjà vu as she and her younger brother explore the medieval village and abbey. She is even more disturbed when she is confronted by two unusual young men, one who insists she has a sacred mission, and the other who will stop at nothing, even murder, to prevent her from fulfilling her destiny. When the oddly-dressed but alluring Nicolas slips Katelyn a strange medallion, she is whisked back through time where her Watchmen hosts tell her she is the only hope to save Mont Saint Michel. Even worse, she learns that those trying to destroy the mount are led by a fallen angel intent on learning the mount's closely-guarded secret. Katelyn is torn by feelings of anger at being taken back in time, inadequacy at finding a modern solution for a medieval problem, and responsibility for the mount’s starving inhabitants. She is also perturbed by her surprising attraction to the ill-tempered Nicolas. Will she stay to learn why she was chosen by the Archangel Michael and find a way to save his mount? less
