Book 2 in the Winternight Trilogy.
This one continues with the story of Vasya to whom we are introduced in the first book. Like the first book it's a Russian fairy tale, so set in Russia with much description of snow and dangerously cold temperatures, demons, fairy folk (domovoi), ghosts etc. We get to know a lot more about the winter King, introduced in the first book by Vasya's nurse and we hear more about Russian tradition and much about horses.
It's just as entertaining a read as the first one and I'm looking forward to the third one.
I chanced on this description on Amazon
In a village at the edge of the wilderness of northern Russia, where the winds blow cold and the snow falls many months of the year, an elderly servant tells stories of sorcery, folklore and the Winter King to the children of the family, tales of old magic frowned upon by the church.
But for the young, wild Vasya these are far more than just stories. She alone can see the house spirits that guard her home, and sense the growing forces of dark magic in the woods...
and knowing that it's just the sort of thing my daughter loves got for her as a Christmas stocking present. She adored it (she's well grown up) and passed it on to me and I have to say I loved it too. it's not wildly original, there's nothing stupendous about the writing and I'm sure someone who knows Russia and its folk tales would pick a lot of holes but it's one of those books that throws a spell.
I hate reccommendations thgat go, 'If you liked...' but honestly, in this case, I can't help saying that I think anyone who loved The Night Circus (which I did) is really going to enjoy this too.
