This is a good Highlander romance, with a likeable couple. I also really liked little Lily, Rowan's daughter.
It was probably fairly common for that time period, but WOW did Arline have some bad arranged marriages! I did think, though, that she should have been smart enough to figure out that it wasn't her fault they didn't work out -- it was because the men were not good matches for her, and a couple just not good men at all.
I liked Rowan, and his loyalty to his first wife was sweet -- but it did get old when he kept telling himself he couldn't fall for Arline.
The ending was a little confusing, with the stuff about the "shadow men" -- Arline had always been told they were her protectors, but maybe not? I won't give any spoilers, but I could have used more information on them and their reason for choosing Arline.
Overall, I really enjoyed the book. It is an entertaining Highlander romance. It does have some violence, but that is accurate for the time period. The story does have sex scenes, but they are within marriage, and are not very explicit at all.
