My book is about 3 sisters: Alex the oldest, Stevie the middle sister, and Joey the youngest. Alex is known as the actor in the family but when she finds out the sisters' school play is the musical Once Upon a Mattress she might not try out for the lead part because of the princess's name: Winnfred Woebegone. But when Alex finds out that Stevie is trying out, the 2 sisters compete for the lead part.
