Query: A book for a 13 year old, not an adult

This book is suited for 13 year olds trying to decide if they should pet sit or baby sit, not for adults who are trying to decide on pet sitting as a business. It also seems to be aimed at readers with little to no pet experience. The chapters are one page long, in a few cases, 2 pages.This book is a total waste of money.
