I feel like my attention span is waning, because it seems like every thriller that I read is just way too long. The Second Mother clocks in around 430 pages, and this story would have been way better if it was condensed into about 250 or even a little less. Part of this was that the author described so many monotonous details that just didn't need to be included in the story. I read a review that someone posted here on Goodreads about the dog, and the person was right- there are SO many mentions of the dog, Depot. I know this sounds exaggerated, but I literally cannot remember the main female character's name, but I remember the dog. I'm all for a solid dog character in the story, but I don't need to know every time the dog takes a drink, or moves from one room to the other. There is also a lot of exposition in this story, and it takes about 200 pages for anything to really start happening. By this point, I was kind of bored of the story, and I just needed something to happen before deciding to call it quits. There is a plot line of a somewhat sinister child, but even that storyline fell pretty flat for me. I have said it before but its worth repeating- I also loathe stories with a million characters- there was the Hempstead family, the main character, her husband, her new potential love interest, THE DOG, another teacher, Peter, Eddie, Eddie's parents, and more. There was just too much going on here for anything to be really developed. By the time the twist was revealed, I wasn't really impressed. I give this one 2.5 stars, rounded up to 3. Thank you to the publisher for sending me a free review copy in exchange for an honest review.
