The oceans overflowed, swallowing the plains.

Earthquakes shook the continents, submerging entire regions in swollen waters. Now, people live crowded in densely populated cities. The only ones who have any space are those who live in the depths of the ocean, the Dark World.

Tai has spent his whole life beneath the sea, helping his family cultivate the ocean floor. But when the outlaws attack his settlement, Tai fights to save the only homeland he has ever known. With the help of Jemma, a girl from the Upper Land who has come below the surface of the sea to search for her brother, Tai risks reaching the dangerous underworld of the border and uncovering some dark secrets of the Dark World... secrets that threaten to destroy everything.

In the Dark World, Kat Falls has created a mesmerizing universe where the depths can be dangerous, darkness can be deadly, and sometimes extraordinary powers are required to survive.
