Real Elves: A Christmas Story by Helen Smith
Real Elves is my first Christmas read of the year and it was a cute little mystery, a little silly maybe, but it has a light-heartedness that fits Christmas. And I would love to visit the Magic Forest, pick a golden apple, and see Santa. It's a short story, only 35 pages or so, so I don't want to give away too much of the plot. I will say that there's no violence and it has a happy ending all around.
I've read a couple other stories featuring Emily Castles. She's smart, funny and a bit quirky, but I don't think you actually get much of a feel for her characters here, it's more about the magic and mystery, not the recurring character. That does mean it works well as a stand-alone though. It'd be a nice gift to sneak into a stocking or a small gift exchange....
