Referring specifically to A Thousand Splendid Suns, the quotation is the promise that Tariq makes to Laila in Chapter 50. Laila has decided that she wants to leave her tranquil life in the relative paradise of Murree, Pakistan for her war-ravaged home in Kabul. She is unsure of Tariq's response, and she only wants to return if Tariq is willing. She should not have had to ask. Tariq has always loved Laila, and she has always dreamed of a life with him. He knows that she has looked past his missing leg, and his days in prison, and he already has returned once to Afghanistan to find her. Knowing the terrible life that Laila has already endured with Shaheed, Tariq is not about to let his true love down now. Perhaps there is nowhere worse to return to than Kabul--symbolically, the end of the world--but Tariq will willingly follow her there.
