The theme of this book is sadness. Rob is the main character. Rob's mom has died and he then moved to a new city with his dad. Then, he was walking in a forest and found a tiger in a cage, which made him feel excited. H asked the owner if he could feed the tiger. Then Rob started to visit the tiger everyday. Rob unleashed the tiger thinking it would not attack him. This is where the bad part happens. I think 3rd graders should read this book because it is interesting. Kevin E., Grade 6
