I read the series on chronological order and enjoyed it. Getting to the end of the last book was sad, but on the bright side I read pretty slowly (a few pages a night before bed) and have a terrible memory for fiction so starting the cycle over and reading each book again in sequence is very nearly like reading them all again for the first time.

Thanks!
