Then/now story—-one part fantastic!

I’m struggling with my rating on this book. The story is written in 2 parts.. a then and now. The “then” being a young hero and heroine that meet at band camp under circumstances that wouldn’t have brought them together otherwise. The relationship is passionate and sweet and just everything. I loved every bit of it.

The “now” is a poor woman who meets a rich rockstar and reads like many other rockstar romance. The story is mediocre and somewhat boring.

I’m so upset because if I could rate these separately the then would be 4.5 stars. The now would be 2. So rating at a 3 doesn’t seem fair to either part of the book.
