Self-help ✦ Penny’s Take
The Secrets of Success in Marriage
John Gatungu Githiga · 2024
Githiga's research foundation — interviews with hundreds of long-married couples across four continents and multiple faith traditions — is a genuine strength that distinguishes this from the typical marriage advice book written from personal experience alone. The cross-cultural scope is rare and valuable, especially for counselors working with diverse populations. The lack of independent critical reviews and the self-publishing press are real limitations, but the author's academic credentials and 53-year marriage provide credible anchoring.
