Sol and Alexia are friends, although Alexia is slightly older than Sol. One day she asks Sol to invite her over to play at her house. Sol is hesitant as she feels she ought to be the one issuing the invitation, but she eventually decides to mention it to her mother, who also feels in a difficult position. So Alexia comes over to Sol's house and they begin to play. A book that magically deals with a critical issue for children: the need to have your own values and to learn to defend them. This is what happens to little Sol when, hoping to please her slightly older friend Alexia, she goes along with all Alexia's whims. Sol seems to rely on Alexia even though she doesn't like her, but she hasn't learned this important skill, how to say 'no'. This is why the author turns to fantasy with the character of a fairy. A fairy who lives in Sol's wardrobe and teaches her how to say 'no'. Nothing more, nothing less. 'No' if she doesn't like something.
