The title says it all, Christmas castle in Scotland. It was so cute, lighthearted, and exactly what you need for the holiday season. It was fun getting to go along with Izzy and her mom preparing the castle for Christmas and turning it into a hotel after it was left to Izzy by a great uncle. I loved the found family that was made during the rush to prepare the castle for its first guests just in time for the holiday season. The mystery of the missing sapphire necklace was an unexpected but fun addition to the story and a fun little history lesson too. I adored this book and it is going to be added to my list of Christmas book rereads for next year.
