Series: Hawkenlye #4
This mystery at Hawkenlye centres around a new unlikable nun, Alba, and her two sisters, who have recently arrived. There's something off about her, so Abbess Helewise goes off to investigate her background. Meanwhile, one of the pilgrims has been murdered.
Learning about the background of Alba and her sisters was interesting, but I don't know if I quite forgive the author for bringing up the stupid Forest People at the end. At least there was no overly psychic stuff.
I read this for the 16 Festive Tasks Square #1 Dia de Muertos/All Saints Day "A book that has all the colours (ROYGBIV) together on the cover".
