This book has such a unique premise (a mother traveling back in time to figure out why her sons commits murder), and I had a terrifically fun time reading it. It had excellent red herrings and misdirections, and the perfect amount of satisfying reveals. I liked Jen as a main character and how realistic her sleuthing was, and also the themes of parenthood and the emotional weight of missing out because of the busyness of life. A fantastic read!!
