Tía Lola has been invited to teach Spanish at her niece and nephew’s elementary school. But Miguel wants nothing to do with the arrangement. On the other hand, Miguel’s little sister, Juanita, can’t wait to introduce her colorfully dressed aunt to all her friends at school—that is, if she can stop getting distracted long enough. Before long, Tía Lola is organizing a Spanish treasure hunt and a Carnaval fiesta at school. Will Miguel be willing to join the fun? Will Juanita get her head out of the clouds and lead her classmates to victory in the treasure hunt?
