This is a story about three sisters who were born with unusual abilities and pursued by their Aunt Rose because of it. When one of the girls gets captured the other two must fend for themselves in the foster care system, waiting for their aunt to come back for them. Present day, to alleviate her guilt, Brooke Martine tries to solve the mystery of another missing girl in their current town, a girl that disappeared over seventy years ago. But a spy is observing Brooke and her sister all the while. They were much too interesting of subjects to be left alone for long.
