Serenity Mitchell has known Marc Spector all her life. They were next-door neighbors, childhood friends, first love, and a married couple. However, after Marc joined the military, their relationship became strained, and they went their separate ways. A few years later, Serenity lost contact with Marc, left America, and moved to England. Immediately, she started to work at The National Gallery as a Tour Guide, where she met a man who looked oddly like her husband, but his name turned out to be Steven Grant.
