Bakkian Chronicles, Book I - The Prophecy

Dragons, griffins, and BNPs (Bugs of Nightmarish Proportions). Never in their wildest dreams could they have imagined what was in store for them.
After learning he had inherited an enormous mansion and a huge tract of land from a reclusive set of relatives, Steve and Sarah Miller decide to take a few days off to investigate their new-found fortune in the quiet resort town of Coeur d'Alene in northern Idaho.
While taking inventory of the vast manor, they discover a unique set of doors on the top floor. Mistaking them to be an ornate decoration, the doors are accidentally activated, presenting the two new homeowners with a tantalizing decision: step through or ignore? What harm could possibly befall them by simply walking through an open door? Curiosity getting the better of them, they step through, and both husband and wife are sent on a one-way journey to a land of unimagined wonder!
Realizing they were now stranded on a world populated with creatures that should exist only in one's imagination, they enlist the aid of the local king and queen. Their troubles continue to escalate, however, as it is revealed their arrival had been long foretold by an ancient local prophecy, bestowing upon them the status of Royal Bodyguards to the young crown prince.
Stuck on a foreign world where mythical creatures abound, trying to avoid being attacked by griffins, and hoping to impress a living, breathing dragon, the newly appointed babysitters must find a way to return home soon before harm could befall the young prince.
Some days it didn't pay to get out of bed.
