I just finished reading this book the second time with the class and I enjoyed it very much. Claudia is my favorite character because I think she is a lot like me. She likes adventure but at the same time she like having routines and schedules. Plus she has annoying brothers like I do.
My favorite part of the book was when Claudia and her brother Jamie were frantically searching through Mrs. Frankweiler's files for clues to the 'angel'. I didn't like the ending though because I wanted to read more about what happened to them when they got home.
Overall it was an adventurous book :)
