Steampunk, Zombies, and Romance... Serendipity Blite inherited her father's crackerjack shooting skills, while her sister, Bloom, got his knack for mechanical engineering. The siblings' talents make them a formidable pair capable of surviving the apocalyptic aftermath of the Dead Disease. Their skills also attract the unwanted attention of Moll Grimes, a ruthless woman intent on building a new empire in a city infested with undead. When Bloom goes missing, Sera suspects Moll has something to do with it, but attempting a rescue mission on her own would be suicidal. Sera seeks help from a band of unlikely allies, including Erik LaRoux, an enticing young man with a curious scar, and a collection of alchemists obsessed with developing a cure for the Dead Disease. Sera's alliance with Erik challenges her old ways of coping, and so do his kisses. Her fierce independence won't be enough to save her sister. But as she opens herself to new possibilities, an unfortunate accident sets Sera teetering on the edge of a deadly abyss. Surrendering to it would bring an end to her grief, pain, and fear, but surviving could mean finding family, love, and maybe even a cure.
