Very much in a vein of The Girl on the Train and other recent mysteries with potentially untrustworthy female narrators, Under the Harrow takes us through a murder investigation from the point of view of a woman who might not be entirely trustworthy, and who certainly doesn't make the best decisions, although her intentions are generally good. 
 This was a murder mystery which kept me intrigued throughout (I read it in 3 nights), and although I felt certain I knew who the murderer was not (and was correct in my assessment), I didn't know who the murderer was until the pieces came together in the final third of the book to a satisfying conclusion. Plus, in addition to being an involving murder mystery, it also was a moving depiction of grief, and how we handle the loss of our loved ones, especially when we discover the things we didn't know about them in the aftermath of their death.
