"The genuinely hilarious Paul Rudnick" (Gary Shteyngart, New York Times bestselling author) returns with a witty, insightful new novel about the joy, delight, pain, and absurdity of love in an age of cynicism, divorce, and digital madness.

A tech billionaire and the flight attendant he's marrying. A TV superhero who used to be married to the flight attendant. A Manhattan book editor and the sensitivity associate who got him fired. A twenty-three-year-old wild child prodigy who's perhaps the savior of American literature. A vengeful Arkansas sheriff who sells a vitamin-enriched, ten-pounds-off-today demulsifier. A Wall Street bro who raps on TikTok. Two dentists--possibly stalking each other.

What do these people have in common? Invited or not, they're all headed to the most anticipated destination wedding ever, on the billionaire's private island, to seek romance, to cause mayhem, and to figure out everyone else's futures and maybe even their own.

Find out what happens in Paul Rudnick's heartfelt new novel, which dares to pose the question essential to anyone who's ever been in love: What Is Wrong with You?
