The Edge of DarkPamela Hartshorne2015

Be careful what you wish for. Jane believes in keeping her promises, but a deathbed vow sets her on a twisting path of deceit and joy that takes her from the dark secrets of Holmwood House in York to the sign of the golden lily in London's Mincing Lane. Getting what you want, Jane discovers, comes at a price. For the child that she longed for, the child she promised to love and to keep safe, turns out to be a darker spirit than she could ever have imagined.
Over four centuries later, Roz Acclam remembers nothing of the fire that killed her family - or of the brother who set it. Trying on a beautiful Elizabethan necklace found in the newly restored Holmwood House triggers disturbing memories of the past at last - but the past Roz remembers is not her own . . .
