As soon as I read the opening lines of Lisa Brackmann’s new China-set crime thriller, Dragon Day, I knew I was going to enjoy it every bit as much as I had anticipated. At initial glance, the book indulges in the two ultimate China clichés — that “dragon” title and its red cover —but with those first four sentences, Brackmann delivers a big wink to her readers: Don’t worry. You might think you know what’s coming, but you have no idea.
