It’s not like someone would seek out this book looking to find advice on how to damage their marriage, but it definitely piques the curiosity of anyone trying to understand how easily a marriage can go awry. How to Get Divorced by 30 is Sascha Rothchild’s personal tale of her short-lived marriage. Surprisingly, it’s not a man-bashing book picking on her ex-husband (some of his faults are mentioned, but not focused upon).
