According to Variety, the book is set in a near-future world in which rising ocean levels and natural catastrophes have led some people to homestead on the ocean floor, and kids to develop supernatural powers. The story centers on an underwater teenage boy and a surface girl who join forces to uncover a government conspiracy.
The project fits in well with Disney's new mandate to create family friendly fare that can be exploited across the company's various platforms and spawn sequels.
Two books had initially been planned, but could now expand to more installments.
No production date has been announced.
