This book was co-written with Louise Penny of the Inspector Gamache series of mysteries. This is exactly the kind of book you think it’s going to be from reading the cover: a diplomacy-based thriller w/ a dose of difficult decisions and cameos of a few people from the Penny universe. And the main character is a middle-aged Secretary of State who has to use her diplomacy chops to get to the bottom of a global disaster-in-the-making. I liked it, but it didn’t go anywhere I wasn’t expecting.
