2089, four kilometres below the ocean surface . . .

Underwater stations are home to hundreds of miners, engineers and biologists, all tasked with excavating and processing the miracle bacteria that is the solution to the energy crisis, ProLEC.

Betty, a miner, is at the bottom of the pecking order despite her years of experience.

Maia, a newbie engineer, knows she has the smarts to become a ProCORPer and make it to the very top.

Audley, a biologist, is on track to become the youngest science lead ever.

But something is very wrong with the ProLEC. Peaceful sea creatures are becoming bloodthirsty fiends, unprecedented power cuts and tremors wrack the station and as the three grow closer to the truth, and to each other, they are in far more danger than they could ever imagine.

The first in a thrilling new series perfect for fans of Ben Oliver, Neal Shusterman and Wren James.
