This book focuses on the unique circumstances that surround being a middle child. While the main character in the book, Kali, is a dog, she finds herself experiencing many of the same feelings that a middle child might experience. Kali feels that she is plain compared to her sisters, that she is always bossed around, and that she is the victim of favoritism. However, by the end of the book, through the encouragement of her friend Arrie, Kali comes to realize that it is being in the middle that makes her special and that in the middle is right where she wants to be.
