3.5 stars rounded up because, well it's Mary Balogh!
This is a lovely romance, and Mary Balogh does a masterful job conveying the reality of everyday life for a blind man in the early 19th century. It's also a great marriage-of-convenience story between two people who really don't want to get married to anyone. I enjoyed once again seeing the members of the Survivor's Club.
My only criticism is that I never really bought into the idea that these two people would part according to the terms of their 'arrangement.' Thus, there was no great drama in the story for me.
