Can two genius kids find the mysterious Sun Stone before it's too late?

When Mike and Sam discover a message leading to ancient treasure on an uncharted island, they plot to escape their orphanage to hunt for the treasure. With no time to lose, the genius boys must fix up an old plane and fly it to the island before the cruel administrator, Ms. Schwartz, can stop them.
Upon arriving, they quickly find themselves in over their heads when they encounter a tribe of large lizards intent on sacrificing them to a malevolent entity named Mosa Laga. With few supplies and no contact with the outside world, the boys must rely on their wits to survive. But that may not be so easy, since they're not the only ones seeking the mysterious treasure.

Secret codes, talking marsupials, a powerful relic...It's an adventure you'll want to read again and again with its exciting action, delightful characters, and timeless themes of friendship and family!
