I love this book because its about Dr. Ruth's life and I love books about peoples life! I thought this book was intresting because Dr. Ruth kept telling her grand children stories about her life when they were in a sitation and how she got her braveness or something like that. It was an amazing story for me!! I hope lots of other children who read Roller coaster grandma like the book as much as me! ( :

This book was.. absolutely.... AMAZING. Ruth's story was adventures, Sad, Happy, and so much more. Ruth lives across the street from me. I can't wait to tell her how good the book is. You should definitely read the book.

I loved this book since it like traveled back in time. I would recommend this book to anyone who likes books that show the present and past.

I really enjoyed this book.I thought it was good but I think it should be longer.I also liked when she told a story, because then it showed what challenges she overcame.It was a graphic novel which I liked.Overall this was a pretty good book.

it was awsome!
