In the last city, Mammon, the sins of past lives are inked onto the skin of every man, woman, and child with tattoo-like birthmarks. The more skin the markings cover, the deeper their sins, and the less trust they’re given. Trust that Dias Drake, a young man with 24% of his body covered in markings, will need if he wants to realize his dream of becoming an explorer. However, in Mammon, someone that heavily marked will find gaining trust near impossible, and so, a storm rolls over the city when the marked underclass organize.

Shouts and raised fists call for every heart to be counted. Will Dias be counted among the marked in rebelling against the tyrannical SAFE Act, join the unmarked who hold his dream in their hands, or with everything to gain and nothing to lose, will he be able to keep a distant promise to not be blown away with everyone else?
