I won't rate it, because it wouldn't be fair to the book, which is interesting, but very much not my cup of tea. I like slow burn romances, but this is a very slow burn, a very very slow burn. I mean at one point I started to anticipate 'To Be Continued...' at the end of each chapter. I lost interest at the 2/3 mark of the book, but skimmed to the end.
If you like romances like this, then it's worth it.
