Olive's Ocean

I have two 5th graders in my class that are in my book club. We pick books to read and discuss what is going on in the book. I asked them a few of the discussion questions and this is what they said:
What character was you favorite? They both said Martha the main character, because she is smart and becoming mature in the book.
What character did you dislike? Since we are only part way through the book, one said the dad because he always walks away when he is mad. The other said the brother, because he isn't with the family as much anymore.
Do you like this book? Both said yes because they can relate to what Martha is going through. They enjoy reading about the "problems" like YAL discusses. They were bothing enjoying finding out what would happen to Martha.
Would you read something else by this author? Yes because they like the language he uses and they like the characters he creates.
