I've just finished reading Ghost Drum, which was originally published by Faber in 1987 and won the Carnegie Medal. So it's thirty years old - but it doesn't feel it. It feels intensely fresh and vivid.
Like The Snow Child, it has its roots in Russian folklore. And like Northern Lights and La Belle Sauvage, it features a shaman - well, several - and the ghost drum itself has a good deal in common with Pullman's alethiometer. I had been thinking how interesting it is that serendipity often leads you to books that link up with the one you've just read - but I guess it's actually the other way round: Ghost Drum had been on my Kindle for a little while, and I was prompted to read it because I vaguely realised that it had links with The Snow Child and with La Belle Sauvage.
But it's a very different book from either of those. It's like a piece of embroidery, worked with rich jewel colours on a piece of dark velvet, intense and vivid. It's remarkable.
I was going to write a proper review, but I came across this one by Julia Jones, and it says everything I would have said and more, so I'm just going to point you towards it here.
But one last thing. This book won the Carnegie, and it's wonderful - but it's out of print with traditional publishers. (Though Susan Price has published it independently herself, together with its two sequels.) Why is it out of print? I can just see the three books bound together and illustrated, perhaps with woodcuts - it would make a beautiful book!
