The Great Marriage Tune-Up Book

This is the rare self-help marriage book that backs its quizzes and frameworks with fifty-plus years of peer-reviewed research, and the endorsements from Howard Markman and William Doherty are not throwaway blurbs — these are serious scholars. The self-assessment tools make abstract marital science immediately actionable, which is exactly what couples who feel stuck need. It can feel clinical compared to narrative-driven approaches, but that rigor is also its strength.
