This is true Tamara Allen sweetness here: a quiet little story full of hope in a bleak time.
Sutton and Jack are WWI veterans trying to figure out how to get back into civilian life after the war. Jack runs an emporium which is struggling because of the economic times. He's also suffering from PTSD, unable to sleep most nights. Sutton suffered a hand injury that has prevented him from getting back to playing the piano, and he's running out of ways to make it on his own in NYC.
I really liked the way Ms. Allen took her time with this story and building up these characters and their relationship, so that while this is another one-month romance, it didn't feel rushed at all, and it actually felt like a lot more time had passed. She really pays attention to the details, like the "treatments" for PTSD and the "health advice" for influenza, and makes sure the characters feel like they're from the time period. Normally, when this many side characters are tolerable of Jack and Sutton's relationship, I'd bemoan "gay okay" revisionist history in M/M, but Ms. Allen never loses sight of the consequences, not just of the general public but of the law as well, if the wrong people find out or decide to spread the word. Plus, it's New York, where almost anything goes. There's also a variety of different ways that the characters react to it when they find out, so they're not exactly 100% on the Rainbow Train even when their responses are mostly positive.
I also liked that Sutton wasn't the wide-eyed country boy, and that Jack wasn't the "corrupting" influence his friends teased him as being. Though they'd both served in the army, they didn't come out of it tough-as-nails warriors like you see so much of in contemporary stories. You can see the weariness on them both, and Jack especially had a hard time forgetting the things he saw or the people who died so he could do his work. They were tired of fighting and eager to put it behind them.
The narrator, Meral Mathews, has a nice old-timey quality to his voice that suits the story. I do wish he'd made more of a distinction between the various voices, but I was still always able to keep track of who was speaking and which POV we were in.
