Since Summer Reading's got some serious dragon power, I thought I'd mention a few teen fantasies. Great segue, huh?
The first is Robin McKinley's Newbery Medal winner, The Hero and the Crown, which was also an ALA Notable Book and ALA Best Book for Young Adults book. It tells the story of Aerin, a princess--and an outcast--who grows up to defeat dragons rather than become a queen. The story takes place in a land called Damar, and is a prequel to another of McKinley's Newbery winners, The Blue Sword. See? There was a dragon in that one.
Secondly, I'd like to mention the Books of Pellinor, written by Alison Croggon. The series is a quartet, and takes place is a civilization which Croggon tries to convince us once existed, sometime 10,000 years ago. She even includes fake citations, as if she were doing research in a library with its ancient manuscripts. The first book, The Naming, starts us off with the main character, Maerad, and her companion, Cadvan. The second continues their story, and the third focuses on her brother, Hem, and his mentor, Saliman. The fourth concludes with the siblings united, and working against evil. Unfortunately, there aren't really any dragons, though we do encounter some talking animals.
By the way, if you haven't seen them yet, check out the dragons in the Downtown Youth area, as well as at the West and Malletts Creek branches.
