I liked the protagonists. I enjoy seeing characters being competent. :) Griffin's physical/magical(?) injuries during World War I had disrupted his sense of balance and at times caused muscle weakness in his legs. So sometimes he'd use a wheelchair, and sometimes forearm crutches. Some casual observers who saw him using the various mobility aids at different times had unpleasant feelings towards him.
I'm familiar with trying to get a walker to stay hanging on the back of a wheelchair. I envied Griffin the magic that let him make sure the crutches would stay attached to the wheelchair. My own injury was more like that of another character in the world of Albion. Like Gabriel Edgarton, I broke my ankle badly. Modern-day surgery and then physical therapy helped me get a lot of function back. I remember that temporary disability, though, how a wheelchair let me have more use of my hands and was less exhausting than using a walker.
Griffin's mental and magical abilities were intact, but he needed to prove himself to doubters. Annice was an expert in an industry that was dying, the carving of jet. Also, there was prejudice against women carving jet. Annice wanted to do the work, though. She wasn't aware of good options for other jobs. So both protagonists faced challenges.
The romance was a pretty slow burn. I was okay with that, though. The situations the characters were in were interesting, and so was the dialogue.
