Merriment and Mayhem is definitely an improvement over the other Christmas novellas I have read so far from this collection. This was a silly fun time, full of chaos, and I loved being taken for the ride. It was on the shorter side of these novellas, and there was a little too much miscommunication for the story but on the whole I'd recommend this instalment. I haven't actually read from this author before, but I would definitely be up for reading from them again.
3.5 stars
