Portia Avatar, a girl detective is on the case to find her father, Patch. When Misty, a new student arrives, she brings a case along with her. She tells Portia her case is top secret, and somebody's life is at steak. Portia spends time with Misty in school and out of school. Portia's best friend, Amy, starts to become jealous. Portia has to juggle her two cases and keeping her old friend.
Portia's Exclusive and Confidential Rules on True Friendship was written in vivid detail. The characters were unique and interesting. The author used fantastic comparisons and used magnificent describing words. I could not always connect to the characters because it seemed they acted younger. I believe younger kids would enjoy it more. As the book progressed, Portia learned about the meaning of true friendship, which is a great lesson to teach through a book.
