Imagine this: Your parents have been kidnapped! To rescue them, you must dissolve yourself into the water of a secret hydro-portal called the Water Door, flow through a wormhole in space to another planet, and bring back your family's legendary heirloom-a giant blue diamond.
Are you ready to go?
Jeremy and Joshua, ages 11 and 12, are staying at their grandparents' farm when they discover The Water Door-a hydro-portal that transports them to the distant planet, Tetherae. Once there, the brothers embark on an exciting adventure through the Wilds of Tetherae that includes a fabulous treehouse, fierce dinosaurs, enormous giants, underground caverns, and mystical castles. Using their new Tetherae abilities, they must find a legendary heirloom diamond to rescue their parents from their evil uncle who has kidnapped them before time runs out.
