Sheltered teen Jack Pepper receives a nautilus shell from his estranged grandmother on his fourteenth birthday. When he holds it up to his ear, he’s given coordinates to the middle of the Atlantic Ocean along with a time and date in the not-so-distant future. He embarks on the journey of a lifetime along with his new best friend Bowie Blackwood, a fearless, street-smart runaway.

A harrowing voyage combined with supernatural intervention transports the boys to medieval Atlantis. Upon their arrival, they are summarily captured and sentenced to death for espionage–following obligatory torture, of course. They are pardoned by the mystic leader Master Lumens who’s been expecting them. They each have a higher purpose to fulfill, but first things first–a good education.

They are enrolled at Strongthorne Academy where they will learn to become knights if they can survive the four-year curriculum, goblins, enemy troops–and prom. For fans of Rick Riordan.
