Book 2 was better in the sense that the author explores how family dynamics can influence a couples trajectory both good and bad. This couple's love endure 8 years of missed opportunity because they didn't have boundaries and each had taken a position that was counter productive to their best interest. They do eventually get to an HEA, healthy family boundaries and a position of putting each other as their priority.
I have really enjoyed these books! The characters all have their own issues, but they work through them. I love how despite going through hurt and pain, they found a way to stand strong on their own and together as a family! Amazing!
