It's diversity week at Amelia's school, and she has no clue what it means or why it matters. Every day, she's introduced to cultures, cuisines and customs that push Amelia outside her comfort zone and test her preconceived notions about people and places. Is Mei really asking me to bow when I introduce myself? Is Rosa really celebrating toes, and how the heck do I eat something wrapped in a cornhusk? And why is Malia's mom gyrating in a grass skirt? Amelia has lots of questions (and a few concerns), but the more she experiences, the more she realizes how diversity makes life more fun. She also discovers that differences shouldn't divide people because everyone shares something in common.
