From NPR, a review of Ariel Djanikian’s debut novel, The Office of Mercy, published on February 21 2013.

The government in question here is America-Five, one of a series of heavily guarded, technologically advanced communities that were founded after a worldwide disaster essentially destroyed most of civilization. America-Five is an attempt at a utopia; its scientists are at work on making humans immortal, and its citizens have only occasional attacks from tribes of people from “the Outside” to fear.

The young Natasha is assigned to work in the Office of Mercy, which is in charge of killing all the Outsiders it can find. Like everyone in America-Five, she’s been taught this is a necessary act of kindness. But when she’s sent Outside on a mission, she meets members of the Pine tribe, and starts to question the humanity of the government’s constant “sweeps.”

Amazon’s description has this fascinating paragraph:

The Office of Mercy is speculative fiction at its best with a deeply imagined, lush world, high-stakes adventure, and romance that will thrill fans of Suzanne Collins, Margaret Atwood, Justin Cronin, and Kazuo Ishiguro.
