I finished it about 2 months ago but did not take the time to review it it was a good book. It introduces a new character called Eustace which is a nasty little boy and that sums up a substantial part of the book. The history focuses on a trip that the now king Prince Caspian takes looking for some of his subordinates. It's full of jokes and more context on some of the characters from the last book.
The book closes with the kids returning home as always and we say goodbye to a character that has a lot of that, character.
