In Dragonet Prophecy (Lexile: 740; Interest Level: Grades 4-6), the first book of the Wings of Fire Series by Tui T. Sutherland, the five young dragons (dragonets) of the prophecy are getting anxious about being kept underground and are getting tired of their guardians always telling them what to do. They know they have been chosen to save all of Dragon-kind from the wars of the various dragon queens, but they don't know how they can do that if they have never been out in the world. So, the five dragons figure out a plan to escape and go to find their families and see the world. The adventure upon which they embark shows them that maybe the needed more training than they had received--or even than their teachers could give!
In a series reminiscent of Guardians of Ga'Hoole and Warriors (but with dragons!), this is a promising start to an enjoyable series! (304 pages)
One of the reasons I became an elementary school librarian is so I can read children's books.
