This book was so slow to get into. If it weren't for the audiobook and my reading challenge, I would have DNF'd it around the 20% mark. But, I soldiered on and found a pretty decent story. There were so many characters for me to keep track of at first and such length between their POV chapters that I probably did not get some of the nuance of this book. I feel like I'd have to read it again to get everything from it, and I don't quite want to make that investment. The story had a satisfying conclusion, the historical setting was nice to visit. The writing, however, felt sluggish, but maybe that's supposed to mirror the river around which this story is centered. I'm not sure. Overall, a decent book. I didn't love it. I didn't hate it.
