For the most part, this is a really pleasant book. I like the author's style in general, and I've enjoyed several of her medieval romances.
This novel set in modern-day rural Massachusetts, apparently in the author's current home town. It's written in first person, and the narrator is a woman who works from home in the computer industry, who seems rather reserved with a veneer of calm. Or maybe just socially awkward but still calm inside, or trying to tell herself she's calm... She hits it off with the park ranger who stayed with her after she found that dead body in the woods... She feels drawn to figure out the mystery of a drowning 40-odd years before, because the dead guy was involved in that.
Some of the best parts of the book are the internal ruminations and descriptions of the area by the narrator, who clearly loves the natural environment, and is less comfortable around people. But she's fairly reserved and a little emotionally flat. I didn't feel a lot of deep emo-engagement, either between her and other characters, or to her, as a reader. (Knowing the author's other work, I think the narrator's voice is a consciously constructed character attribute, by the way, rather than being "flaws" in the writing.)
Occasionally, the dialog seems a trifle contrived, and is often too formal for the time/place, with oddly little use of contractions we'd normally find in modern American speech... But it's pretty well constructed overall, and I enjoyed it, even though I can't say it totally bowled me over.
As usual with indie work, I'll mention that the formatting and editing were good. In fact, I didn't stumble across a single typographical error while reading the book, so bravo to Ms Shea (and her copy editor); she wins a Golden Rodent for this one.
