How many words can you fit in a subtitle? For a slew of modern books, the answer seems to be as many as possible. Just look at Julie Holland’s “Moody Bitches: The Truth About the Drugs You’re Taking, the Sleep You’re Missing, the Sex You’re Not Having, and What’s Really Making You Crazy,” Erin McHugh’s “Political Suicide: Missteps, Peccadilloes, Bad Calls, Backroom Hijinx, Sordid Pasts, Rotten Breaks, and Just Plain Dumb Mistakes in the Annals of American Politics” and Ryan Grim’s “We’ve Got People: From Jesse Jackson to Alexandria Ocasio-Cortez, the End of Big Money and the Rise of a Movement.”
