The One and Only Bob

Just released, The One and Only Bob is a sequel by Katherine Applegate. I would recommend reading The One And Only Ivan before reading this book. 
In this book you get Bob's (the dog) perspective. Bob has a great family. He lives with a girl named Julia and her parents Sara and George. George works at the zoo where Ivan and Ruby currently are. Bob and Julia go with George to the zoo to see Ivan and Ruby (Bob's closest friends.) A tornado hits when Julia, George and Bob are at the zoo and it destroys more than half of the zoo! When Bob hears a call from someone he thinks he knows he sets off to find his long lost sister. Will Bob find her? Is it really her or is he just hearing things? 
I recommend this book to 3rd graders and up.
