The Charmed Children of Rookskill Castle
by Janet Fox (Viking, 2016); audiobook read by Fiona Hardingham (Listening Library, 2016)
Another middle-grade fantasy set during the Blitz. The children on this occasion are evacuated to a castle in Scotland and thence embroiled in a supernatural closed-circle murder(ish) mystery. The storytelling is proficient enough but the developing threat is undermined by narrative omniscience.
