Sunny is an expat in Kabul who blissfully runs a coffee shop for other Americans in the country. When Yazmina, a pregnant young woman from a nearby village, is kidnapped and later abandoned near the coffee shop, Sunny instinctively comes to her aid. Candace, a wealthy American, also pitches in, while Isabel, a journalist, chronicles Yazmina's woe. Meanwhile, Halajan, a local mother, is reeling from a forbidden love affair.

After hard luck and some bad choices, Sunny has finally found a place to call home - it just happens to be in the middle of a war zone. The thirty-eight-year-old American's pride and joy is the Kabul Coffee House, where she brings hospitality to the expatriates, misfits, missionaries, and mercenaries who stroll through its doors. She's especially grateful that the busy days allow her to forget Tommy, the love of her life, who left her in pursuit of money and adventure. Working alongside Sunny is the maternal Halajan, who vividly recalls the days before the Taliban and now must hide a modern romance from her ultratraditional son - who, unbeknownst to her, is facing his own religious doubts. Into the café come Isabel, a British journalist on the trail of a risky story; Jack, who left his family back home in Michigan to earn 'danger pay' as a consultant; and Candace, a wealthy and well-connected American whose desire to help threatens to cloud her judgment. When Yazmina, a young Afghan from a remote village, is kidnapped and left on a city street pregnant and alone, Sunny welcomes her into the café and gives her a home - but Yazmina hides a secret that could put all their lives in jeopardy. As this group of men and women discover that there's more to one another than meets the eye, they'll form an unlikely friendship that will change not only their own lives but the lives of an entire country.
