For my very last children's christmas book review of 2020, I can't think of a better one than this one. This sports a light-up Moon - which isn't as impressive as it sounds, but is activated by a hidden pressure button on the cover. It also has a battery accessible (and turn-off-able!) module at the back, so there won't be a time when it runs down and becomes useless.
What I loved about this book, and what put it over the top as the best one I've seen this year, was the silhouette illustrations by Glavin, which are beautifully done; the book is worth getting just for those alone. The girl and her plush toy want to say goodnight to Santa, and end up taking a rather magical and Moonlit stroll through the winter landscape saying goodnight to everyone but. It's a fun and inventive book and I enjoyed it.
