Growing up, I loved looking at the photos in my mother's old Betty Crocker cookbook: the chocolate cakes, the cookie house, even the cheese balls and fondues.

My mother wrote a teen column for the South China Morning Post in the 1950s when she was growing up in Hong Kong. Her name was Lily Mark, but she sometimes wrote under her confirmation name, Margaret Mark. That was how she met my father.

Every writer needs new material now and then, whether it's traveling to Japan, volunteering at a food bank, learning a new language, or trying a new food.

I wanted to write a book about people who have the best intentions and think - really, truly think - that they're doing the right thing. And then they realize that when those ideals come knocking at their windowsill, a lot of times they will suddenly disavow those ideals.
