"I am deeply saddened by Elaine's passing. Elaine was a wonderful agent, and I owe my career to her," Hosseini said in a statement.
"I am forever drawn to family as a recurring central theme of my writing," Hosseini, the Afghan-born author and physician, said in a statement. "My earlier novels were at heart tales of fatherhood and motherhood. My new novel is a multi-generational family story as well, this time revolving around brothers and sisters, and the ways in which they love, wound, betray, honor, and sacrifice for each other. I am thrilled at the chance to share this book with my readers."
