The oceans rose, swallowing the lowlands. Earthquakes shattered the continents, toppling entire regions into the rising water. Now, humans live packed into stack cities. The only ones with any space of their own are those who live on the ocean floor: the Dark Life.
Ty has spent his whole life living deep undersea. When outlaws attack his homestead, he finds himself in a fight to save the only home he has ever known. Joined by Gemma, a girl from Topside, Ty ventures into the frontier's rough underworld and discovers some dark secrets to Dark Life. Secrets that threaten to destroy everything.
