Acquired as a free download from the TOR ebook of the month club. 
 Briefly and among other things an updating of Russian folklore to the first half of the 20th century (view spoiler)[e.g. the early scene with the domovoi getting into the collective spirit of the times, to reflect the mutual ownership of the house of which they were the guardians, is memorable. (hide spoiler)] 
 The author's command of - what feels to this nonexpert like - ballad evocation, folkloric speech within prose- her use of "arc phrases", just for example- enthralled this reader. I enjoyed this book very much indeed- and maybe it deserved more than 4-4.4 stars after all on that and other counts- I will anyway be looking for the other half of the Diptych, and picking up other books of hers, including I expect Refrigerator Monologues when it's out in a month or so. 
 (Started reading around April 10-14, then put it down, mostly finished it in the last week and shouldn't have taken me that long really.)
