Rohaise the Red by Heather McCollum

A Highlander, a lass, and a ghost – oh my!

Fleeing in the night to a small Scottish town, Abigail realizes she’s being followed and takes refuge in an abandoned castle. But the castle is not empty. It’s home to a lady ghost with long red hair, an affinity for handsome men, and the power to protect Abigail.
Kerrick Hay has suffered too much disrespect at home for having joined Cromwell’s rebellion against the crown and a monarch’s absolute rule. As the second son, his only chance of making a comfortable life for himself is by renovating and making the old family property of Delgatie Castle profitable.
When he arrives to find a lass burying a dead man in the castle courtyard, his surprise turns into absolute disbelief when he battles an invisible foe bent on protecting her.
The troubled spirit’s name is Rohaise, and her yearning to live once again is fierce, fierce enough to kill for love and freedom.
