Twenty-five-year-old Madison Chase knows that her job as a tracker is to find dangerous men and turn them over to the proper authorities. She knows she's pretty good at her job-not least because of the special powers and gifts she possesses. But there's a lot she doesn't know. She doesn't remember her early years, and she doesn't know who her parents are. These absences haunt her. Madison's special abilities attract the attention of one particular agency. After several tests of her skills, their interest in her takes a dark and sinister turn, opening the way for a journey of self-discovery and leading her to find the truth of her origin and the destiny she has yet to fulfill. "Sand Castles and Seashores" follows Madison as she meets both Will Matthews, a special operative, and Nicholas, an important person from her past. The trios' lives become intertwined, weaving each person into the others' destinies and creating an intense bond among them. In the end, what do you need-and who do you love-when you come undone? How do you rise above the rubble of a broken spirit?
