In a world blasted and barren, the last bastion of civilization is a fortress-city called Central. Kaine, the city's benevolent arbiter, rules over the people in exchange for his gift to them: Re:memory—a public archive containing humanity's memories of the world before it was destroyed. Rezin doesn't know who he is or why he's in Central, but he does know this: he is a Reaper. His combination of gifts and abilities allow him to decrypt any system and steal information to sell to the highest bidder. His talents afford him a life of luxury until the day he plugs into Re:memory and reaps something he wasn't looking for—something Kaine will do anything to get back.

arth is dying. Luna is uninhabitable. Mars is our last chance. Once considered humanity's future home, Mars hasn't worked out like anybody hoped. Plagued by crime and a terraforming project that's centuries from completion, Mars is a red hell. Denver Moon, P.I., works the dark underbelly of Mars City. While investigating a series of violent crimes linked to red fever--a Martian disorder that turns its victims into bloodthirsty killers--Denver discovers a cryptic message left by Tatsuo Moon, Mars City co-founder and Denver's grandfather. The same grandfather who died two decades ago. Twenty-year-old revelations force Denver on a quest for truth, but Tatsuo's former friend, Cole Hennessy, leader of the Church of Mars, has other plans and will stop at nothing to keep Denver from disclosing Tatsuo's secrets to the world. Hell-bent on reclaiming her grandfather's legacy, Denver--along with her AI implant, Smith, companion android, Nigel, and shuttle pilot, Navya--set out on a quest to find the answers they hope will shed light on the church's true agenda, the origin of red fever, and the mysteries surrounding Tatsuo's tragic death.
