Counting by 7sAudiobook CD - 2013
Willow is a twelve-year-old genius, obsessed with nature and diagnosing medical conditions, who finds it comforting to count by sevens. It has never been easy for her to connect with anyone other than her adoptive parents. Suddenly Willow's world is tragically changed when her parents both die in a car crash, leaving her alone in a baffling world. This extraordinarily odd, but extraordinarily endearing, girl manages to push through her grief.
