The Forgotten Worlds Book 1:
The Emerald Tablet

Benjamin and his best friend Andy are different from normal. They love being able to read each other's minds and use telekinesis to play tricks on other kids. In fact, they are getting all set to spend their entire summer doing just that when Benjamin's mirror starts talking. Suddenly, Benjamin's looking at eight weeks of summer school someplace which can only be reached by a teleporter inside the ugly picture in his hallway.
And that's the most normal thing he does all summer.

The Forgotten Worlds Book 2:
The Navel of the World

At the end of summer school, Benjamin was given one task—find his missing brothers. Should be easy right? But Benjamin can't locate a trace of them anywhere. Then he finds a mysterious file written in ancient Lemurian with his name on it, which wouldn't be so weird except the file happens to be several thousand years old. Who would have known about Benjamin that long ago? And then Benjamin and his friends begin to wonder, have they been looking not in the wrong place, but in the wrong time?

The Forgotten Worlds Book 3:
The Necropolis

The situation in Lemuria is rapidly deteriorating. In fact teleportation between the hidden continent and the outside world has become so dangerous, all agents and their families have been recalled. Although Benjamin is psyched to be living in Lemuria full time, he knows he needs to find his last brother soon. However, between classes, a murderous half-brother, and complications with his friend Heidi, Benjamin can barely focus. Besides, there's only one place left they haven't searched—the hidden continent of Atlantis.
