This entry in the series is difficult to review because the characters and plot are engaing but there are a couple of glaring errors which are quite grating. A stereotypical pinched hyper-religious pair of siblings move into an abandoned house and proceed to intrigue a village which is gearing up for their harvest festival. (Incidentally, the plethora of festivals which this village celebrates is a little unbelievable, but one is willing to give that a pass.) The mysteries surrounding the family and their murders involve layers of past sins which results in interesting reading.
However, the author really fell down on her research for this story: albino humans Do Not Have pink eyes. Albinos have pale eyes but she says "pink" over and over. And the secret passage to an old house is not believable - remove a brick on the exterior of an old house and successfully activate a mechanical lever? Nope.
The series is good enough for light bedtime reading, but not a literary great.
