I originally bought each of these books individually, and it was quite a pain finding all of them. This is a convenient way to purchase these very cute, very fun fantasy stories.
The first book, "Dealing with Dragons", is a very witty, very cute book about the improper princess who decides to live with dragons rather than get married to someone she doesn't even like. Cimorene becomes the dragon Kazul's "princess", doing her chores for her, cleaning out her library, and cooking for her. The story has a lot to do with the relationships between wizards and dragons and in a sense, everything mocks the "real" view. Throughout this book, Wrede is practically laughing at every fairy tale ever written, and it is hilarious.
Book two, "Searching for Dragons", introduces a new character. Mendanbar, King of the Enchanted Forest, needs to go talk to the dragon king (and there's a new one from the last book!). Unfortunately, the dragon king has been kidnapped, so he and Cimorene go looking for her. It's more action filled than its predecessor and has a lot more magic going on.
"Calling on Dragons" is clearly the weakest book in the bunch, though it's. It's least memorable of them all, its new characters are the most boring, and the plot is more of a preview for the final book, "Talking to Dragons".
And speaking of, "Talking to Dragons" once again brings us the fun and excitement the first two books brought. While each of the other books had a gap of time that stretch across a year or so, the gap between COD and TTD is much bigger... Sixteen years! We've got a whole new generation of characters, whether its the cats, the fiery girls, or our (!) narrarator! Yes, TTD is written in first person, which is a first in this series. We truly get into Daystar's head, which is fun and enjoyable. In a sense, TTD continues where COD left off, but obviously much later, and many things have changed.
So if you like rather mocking fantasy stories that are both fun and cute, you'll love this. If you love witches, evil wizards, cool dragons, and awesome characters, than this is a great set to pick up. Just remember that COD is more of a transition book and all will be well.
So go join Cimorene, Mendanbar, Kazul, Daystar, Morwen, the cats, those evil wizards, and the lot by buying this great set!
