I read this book and I'm reading the second book right now since I liked it so much. So the book begins with two best friends named Colleen and Tess. They are about to start a new grade at a brand new school. When they figure out that they are in different classes they start to split up because Tess is in a class with none of here friends and maybe not a nice teacher. But, Colleen is in a class with her old best friend Lauren. Then they invent the Coronado club and they wanted her to be mean to other people to get into the club. So now she is all alone and has to make a new best friend. Then Tess finally finds a true best friend and secret sister named Erin.
This book is about a boy named Leo who works and lives in the Whippet Hotel. Each floor in this hotel has a wacky sort of twist to it. He is trying to look for these special boxes that will help solve the mystery of what happened to Merganzer E. Whippet.
