In the Wicklow Mountains of Ireland, Deeprath Castle is the home of the Darkling Bride, a local legend of a sultry and dangerous woman from long ago whose wrath continues to haunt the castle. When the estate is slated to become a public trust, scholar Carragh Ryan is hired to take inventory of its historic library. Two decades ago the parents of Aidan, the current Viscount Gallagher, died violently at Deeprath... and the case was never closed. Were their deaths related to that of Lady Jenny Gallagher, who died at Deeprath a century before under mysterious circumstances? As secrets emerge from the shadows and Carragh gets closer to answers-- and to Aidan-- will she be the Darkling Bride's next victim?
