A very dutiful daughter Book

Received another copy of this book recently as part of a batch from a UBS. I read it again and I have to say I enjoyed it a lot more than I apparently enjoyed it the first time (when it just got 2 stars from me). Other than the rather sudden about-face for Roger, the hero, from seeming mostly indifferent to Letty in one scene to declaring his love the next time he sees her - maybe I missed something - the book reads quite smoothly, has several interesting characters besides the h/h, and well-written Regency-type scenery and situations as well.
