After global catastrophes have altered the landscape of the world, with waters rising and land masses shattering like glass, there are only two places for people to live: Topside, where humans live packed into stack cities, and that other world, Dark Life, where people live on the ocean floor. Ty has spent his entire life living in the latter. When outlaws attack his home, Ty finds himself fighting to save it. Joined by Gemma, a girl from Topside, the two travel through the rough underworld and discover dark secrets that could destroy everything.
