After too many close calls during his adventures in ancient England, Dave is happy to be safe back home in 1990s Pennsylvania. But that doesn’t mean he’s ready to leave Merlyn and his other friends behind forever. In fact, it would probably be best if he kept his family’s magic mirror close by at all times, just in case. Merlyn could need his help at any moment!

Unfortunately, that moment comes when Dave least expects it, and his decision to keep the mirror on hand leads to dire consequences. This time, Dave isn’t the only one pulled through the mirror’s glossy surface, and when he arrives in Camelot only to discover Morgana has struck again, his unexpected fellow travelers are the least of his worries.

Now, Dave and his friends will have to delve deeper into the past to unravel Morgana’s plot before she can siphon the dragon knights’ essence and destroy the fabric of time.
