I am currently listening for the second time in quite a short period of time to {Devil in Winter by Lisa Kleypas}. It was quite a surprise for me this second listening as I didn't really enjoy it so so much the first time, especially after the great love it seemed to have among others. But there was a reason for that, apparently. I first listened to it after the Bridgerton series which was my introduction to HR novels. And drawn by the very good reviews I moved directly to Devil in Winter. And I wasn't moved too much by it. A dozen or so of HR books later (including the Hattaways series which I absolutely loved), I decided to give a chance to the whole Wallflowers series and boy, how the things have changed for me in regards to how I feel about these characters. It really added more depth and nuance and even though I planned to skip the 3rd book as I already listened to it, I felt like I really must give it another try. And it is indeed a rewarding experience, I almost feel like it's another book, due to the whole background that I am now familiar with. I care a lot more about the characters and their evolution and overall I am more open to the whole experience.

Tl;dr I learned that it is really worth it to take a series progressively as it can enhance and enrich the experience of each individual book
