Whiter Than the Lily — Alys Clare

Invited by his neighbour to meet some new friends, Josse d'Acquin is struck by the beauty of the young wife and the age gap between her and her wealthy husband. But first impressions can be deceptive, and soon a tragic death under very puzzling circumstances sets Josse off on a trail that brings him danger and intrigue.

In order to untangle the terrible secrets from the past, he is forced to venture far from the refuge of Hawkenlye Abbey to the dangerous marshes; a place of killing and bloody legend; home to a strange and brutal race and known to all around by the dread name of Deadfall.
