Pretty generic tale of an eleven year old girl with low self-esteem and a large amount of dissatisfaction with her life who meets a fairy that will grant her three wishes. Of course, the wishes go awry. Which in turn is an opportunity for Philippa to learn something important. The fairy's life is tied to that of a daisy flower and she too is supposed to learn something from this encounter, namely compassion and empathy.
The good old "Be Careful What You Wish For" and "Discover the power of being yourself" and "What you can do when you put your mind to it" are all present. Bland, but nothing wrong with it, per se.
