Sierra Wilson's review of this book nailed it. Willow Chance is a 12 year old genius who is obsessed with the number 7, plants, and diagnosing medical conditions of those she meets. After her parents are killed in a car accident her comfort level is shattered and she forms bonds with the most unlikely characters. However, like "Willows beloved plants ,these are people putting down new roots and rising towards the sun." An excellent read for all ages.
