When I first began working in Kabul, I was surprised by how expats often advertised their work and adventures with what appeared to be a sense of showmanship. I often perceived something vaguely opportunistic in the risks people took, as if they were more interested in the swashbuckling narratives they were constructing (often via social media) than in the work they were there to accomplish. I began to see America's presence in Afghanistan as a neocolonial project that wasn't dramatically different from the British or French colonial projects half a century earlier, with expats living protected lives, largely cut off from the local people while being served and protected by them. 

The scene with the rocket attack in downtown Kabul—when a rocket fired from the mountains strikes the side of the Serena Hotel—very closely follows an experience I had, and all the details were those I observed. Many Afghans I spoke with also helped me construct scenes in the book based on their own stories, such as the suicide bomb attack on the American convoy and the young Afghan who, disoriented by the explosion, reaches down and picks up the jawbone of one of the attackers without realizing what he's done.

I began working on the book in 2009 because I was fascinated with the expat culture of the civilian surge and found myself asking how such a thing could be both civilian and a project created and funded by the United States government with a military goal in mind—to "win hearts and minds" (a trope widely used in Afghanistan, Iraq, and Vietnam).

So much has been written about military engagement—the firefights and the daily lives of soldiers and their homecomings—but I wanted to address the sort of frontier culture that arises in expat communities. These individuals are often highly critical of their governments and of the war, and yet are often a part of the mechanism of that war. Just as a book like David Abrams's Fobbit showed readers the often absurd bureaucratic workings of military life inside the Forward Operating Bases, Into the Sun takes the reader into expat culture, with its war zone visionaries, its cowboy aid workers, its adrenaline junkies, and its world-savers, many of whom are reinventing themselves after relatively mundane lives in America or elsewhere. Later, the book shifts the focus to show how a young Afghan raised during the Kabul aid bubble, seeing the boomtown ambitions around him, tries to make sense of his future and reinvent himself as well.
