This Is What Happened by Mick Herron, 261 pages
When the story begins, rookie spy Maggie is midway through a midnight mission in an office building. It's a tense situation, and the tension doesn't let up even afterward, when Maggie is interacting with her handler. Soon, however, it becomes apparent that everything is not as it seems. This is a quick-moving, high-tension book that keeps you guessing. I enjoyed it, though I would have loved to see just one or two more chapters tacked onto the end, as I'm REALLY CURIOUS about what happened after that last page. But alas, I'll just have to speculate on my own.
