Your favorite book(s)

Everybody has a book that they really like for some reason or another. Share it with us! Tell us the title and the author (if you remember lol). Feel free to write a brief summary of the book-- but don't give anything away!-- or explain what makes it your favorite.

If what you like is in a series, please say which book in the series it is.

Oh gosh, this is making my brain hurt just thinking about it. Uhhh, I don't know. Maybe Catherine, The Great Journey, or Isabel, Crown Jewel of Castille. (Both are books in the Royal Diaries series).
