"Aunt Dolores is getting married, and Mabel and Violet are going to be her flower girls! But scattering rose petals isn't quite what Mabel has in mind"--Publisher.
When Violet conjures a pool for their yard and refuses to make it disappear, Mabel, who is not magical, does not know how to explain this to their parents.
After a long car trip to the beach town where her cousins live, Mabel finds out that Zoe and Mya can see Violet for what she really is. But her biggest worry is what they see in her!
