William Brangham:

From the very beginning of the Syrian uprising, Rania Abouzeid has been one of the conflict's earliest and closest chroniclers.

She witnessed the first days of peaceful civilian protests against Bashar al-Assad, and then his government's brutal crackdown. She was there for the rise of groups like the Islamic State, saw how the intervention of the Russians changed the tide of the conflict, and witnessed the transformation of a hopeful revolution into a grinding seven-year war.

She's now published a new book called "No Turning Back: Life, Loss and Hope in Wartime Syria," and it tells the story of this conflict through the eyes of those who endure it and those who fight in it.

Rania Abouzeid joins me now.
