PositiveThe Boston GlobeAs in any good mystery, the third-person narrator knows more than he lets on; much is hinted and suggested, little is spelled out. The style is spare but pictorial. O’Nan’s historical and topographical research is impressive — the streets, monuments, city gates, even the swallows and the desert wind, the khamsin, are meticulously named. It’s a fine piece of storytelling. I have to say, however, that I did not fully buy Brand as a young Latvian.
