King, author of The Vindico series, as well as The Incredible Space Raiders from Space! can pen fantastic scenes of action, and he incorporates both medieval and science fiction elements to good effect. Dree's friendship with Lourdvang, as well as her ability to ride him and not get burned, nicely complements her accomplishments as a blacksmith, and Marcus shows that his skills at video games can be used to save the day. The Dree's willingness to help Marucs without asking too many questions when he plummets from the sky, combined with Marcus' blithe acceptance of a world rife with dragons allows the reader to quickly sink into the fantastic world of Dracone.
There are a few other books that combine technology with mythical creatures: Savage's Fires of Invention or Diana Wynne Jone's Dark Lord of Derkholm make good follow up reads to this world-spanning novel until the next book in this series comes out.
I could have done without Marcus being bullied in his own world. It's such an overdone trope in fantasy literature. Maybe more sports players would read fantasy if they sometimes saw themselves represented on the pages!
