The Bakkian Chronicles

After learning they've inherited property from reclusive grandparents he hardly knew, Steve and Sarah Miller decide to take a few days off to investigate their newfound fortune in the quiet Idaho resort town of Coeur d'Alene. The inheritance turns out to be beyond their wildest dreams, a vast mansion with gardens. While exploring, they discover a unique set of carved doors on the top floor of their new home.

Nearly a year has passed since Steve and Sarah Miller discovered Lentari through a magical portal in their own home in Idaho. Mikal, the young Lentarian crown prince, is happy, healthy, and adapting well to living in modern America with his bodyguards. However, their peace is soon shattered when Steve gets a frightening message—the queen has been kidnapped and their help is needed! They leave Prince Mikal safe and secure in Coeur d'Alene with Annie, Sarah's sister, and Tristan, his tutor.

It's been four years since Steve and Sarah Miller discovered the magical portal to the kingdom of Lentari and took on the role of guardians to the crown prince, Mikal. The now-teenaged prince is adapting well to life in modern-day America, but their peaceful existence is rocked to the core when they are attacked by creatures not of this world, during a vacation trip. And when a second attack happens, they know they must return to Lentari and find out how someone from there has crossed into their world to endanger their lives.
