“I’m kidnapping a child” is a gripping way to begin a novel, and The Tokyo Suite doesn’t lack for tension. What’s most surprising about it, though, are the forms that tension takes: there’s both the way that one narrator reckons with the consequences of her actions and the coping mechanisms the novel’s other narrator uses to convince herself everything is fine. It’s a compelling thriller, to be sure, but there’s a lot more to be found just below the surface.
