Six responsible adults.
Three cute kids. One small dog.
What could possibly go wrong?

In Truly Madly Guilty, Liane Moriarty turns her unique, razor-sharp eye towards three seemingly happy families. It begins with an innocent invitation to a backyard barbeque... But two months later, it won’t stop raining, and one couple can’t stop asking themselves the question: What if we hadn’t gone?

With Truly Madly Guilty, Moriarty takes on the foundations of our lives: marriage, sex, parenthood, and friendship. She shows how guilt can expose the fault lines in the most seemingly strong relationships, how what we do say can be more powerful than what we do, and how we often don't appreciate how extraordinary our ordinary lives are until it's too late.
