The class that wins the most awards will receive a pizza party. The catch is that the costumes have to be from a book, and Emma, undaunted, is sure she can help her class win the pizza party. She knows she has a great idea, and she recruits her friends Sophia and Javier to play a lion and a wardrobe to her witch. Javier comes up with a terrific wardrobe costume, and Sophia's lion costume is impressive. Unfortunately, two days before the party, Sophia's lion costume goes missing. Emma starts gathering clues, reporting each development on her news station, and pieces together the mystery. Emma is a confident and bright character who is unafraid to shine but also knows how to rein it in. She is surrounded by a diverse cast of characters who do their best to offer guidance and support. Peña's cute and bubbly illustrations capture Emma's energetic sparkle.

Aspiring TV reporter Emma Perez returns with a new mystery afoot: Sophia's lion costume, part of a group costume with Emma and Javier, has disappeared. Without it, their hopes to win the interschool Halloween costume contest are ruined. Still dauntless and spirited, but fortunately less fame-crazed in this installment, Emma heads up the investigation. Spanish phrases and cheerful illustrations are evenly sprinkled throughout.
