Jessie, Hunter, and Georgia Northwood knew summer break would be epic, but they didn't know it would involve dragons and magical lands.

When a mysterious red letter appears in the mail addressed to their mother, things go from normal to crazy. Suddenly, their plans for the best summer ever are put on hold and they're shuttled off to stay with their grandfather for a week.

With boredom driving him crazy, Hunter decides to investigate the off-limits woods at the back of Gramps's old farm. When he's gone for too long, Jessie and Georgia go looking for him. What they find is a portal to a land in great danger...and they're the only ones who can save it.
