Picked this up on Hoopla so I would have something to listen to while knitting.
The story is straightforward and clean: a perfectly happy couple is about to get married and live for a while in the cabin the bride's mother grew up in. While cleaning the cabin, she finds a diary, doesn't scruple to read it, and learns something terrible. She leaves. Havoc ensues.
Now for the meh part: the narration is lackluster and frankly boring. The story itself reads as though a lot of 2017 technology is just kind of in the fabric of life in the 1880s (eg, a guy is freezing after getting dunked in an icy lake, but instead of getting him right in front of the woodstove and stripping off the icy stuff, he's sent to a bedroom so he can change clothes--in a place without central heating. Or someone gives directions like, "Go down the road about a mile and then when there's a fork, take the left." In the dark. During a snowstorm. I guess horses had GPS?) It didn't feel immersive, was the problem.
(A cabin unattended in the woods for fifteen years should have been full of vermin, and mice would have eaten that journal. I'm just saying. It wouldn't be a "cozy" cabin anymore because there would be holes in the roof and squirrels living in the walls. I live in the woods. It's a constant battle.)
Elizabeth's insistence on talking to no one is the real cause of the conflict, and it's never addressed. Moreover, the characters do things like conveniently forget that she has relatives across the state where she probably went -- as in, David actually says, "I wonder why I didn't think of that?" (That's known as a "Signal from Fred" in SFF circles.) And then the conflict ends up solved by a coincidence (Hey, boss, that person you're looking for? My cousin wrote a letter where she happened to give the first and last name AND the address of her employer, who is that person who disappeared all those years ago!)
So, it's okay if you want something clean and short and not terribly preachy at Christmas.
