As you may have guessed, we have a soft spot for dragon books in our household.
The first features dragons on the menu. Lailu has to catch and kill a dragon to cook and serve to diners at her mentor's five-star restaurant, or she'll be forced to cook for his moneylender the rest of her life. I had a hard time reading it. Something about the opening, when the main character looks into the eyes of the dragon she's trying to kill (for dinner) and sees his will to live that struck me as a throwback to the days of the Safari Club hunting big game to extinction. But, it IS fantasy, so if you can read it with that in mind and not think of real-life parallels, it's a good story. There's a larger plot involving an Elven mafioso who's been expelled from the city by the King, and of course there's an annoying boy / rival chef-in-training Lailu clearly develops a pash for.
The second features a boy with a loyal dragon who has to save him (cool!). Sam's master wizard dies, and he has to find a new one. It's an older style of writing, and hard to understand and follow at points, but fans of dragon fantasies may enjoy it.
The third book features such angst-charged dragon teens that they take their hearts out to avoid spontaneously combusting. They're supposed to put them back in once they mature, but they've forgotten they need to do it, and it in the meantime, they've been hunted by humans to the brink of extinction. There's only one left. It's up to the main character, Princess Violet, to discover -- through hidden stories --what the dragon needs and reawaken his memory of what to do or he'll die and the evil Nybbas will finally get free.
This one also is a bit hard to follow, but again, fans of dragon fantasies will enjoy it.
The last is a bit younger than what my two kiddos usually read. It features a teen dragon who runs away from his human "owner," finds his treasure and renames himself.
