I received an ARC through NetGalley and this is my honest review.

I enjoyed this author's previous book but I possibly liked this one even more. Codependent twins! Bog bodies! Dead daughters! Murderous hunger!

The main character is an unmarried companion to an old lady, whose science-minded married sister becomes violently sick and disturbed in the mind after finding an old corpse in the bog surrounding their estate. (A very gothic setting.) You have the creepy atmosphere, the mysteries, and the creeping sense that something is really wrong with Sarah.

I'd say the plot is quite predictable, but that's not really the point, rather the atmosphere and the characterization, which were both worth the read.
