In the book it tells you about a little girl called Jamie solving a mystery about a fairy princess being in her house.
The first clue was that there was sparkles on the floor and only a fairy drops fairy sparkle dust. Then she finds a note that has purple pen writing on it and it says " dear Jamie I love you and don't ever forget it! F.P" and F.P stands for fairy princess.
Next she finds a cup with tea in it and it is proof she's been there. She finds a box that says my prince and has a bunch of pictures inside it. In the bathroom she finds fairy dust (makeup) and a fairy definitely needs makeup. At last her mum calls her and her mum was going on a date and Jamie gets a baby sitter.
I would give it a 9/10 I really like this fairy princess story.
