To so confidently believe oneself to be on the right side of history is risky—for a writer especially. In that balmy glow of self-regard, complacency can easily take root. And good prose demands a measure of self-doubt—the worry that nags at a writer, that forces her to double back on her sentences, unravel and knit them up again, asking repeatedly: Is this clear? Is this true? Is this enticing? This book has a slackness to it that suggests Roy has abdicated some of these anxieties.
