E. L. Konigsberg
From the Mixed-up Files of Mrs Basil E. Frankweiler is set in modern times in the city of New York. Konigsberg chose that setting because the crowd is large there and it would be easy there to get lost.
The characters Claudia and Jamie are children who get into a good relationship as the book progresses, and they begin to agree on things.
The book reminded me that even evil people can learn that doing bad things leads to bad results.
Something that I enjoyed about the book is that it described the characters personalities well. Jamie didn’t like to spend money. Claudia was always anxious to know things. It is important that they were different characters but they learned to work as a team.
