The Highlander’s Enchantress by Violetta Rand

If her cruel and domineering father were to be believed, Kali Bane is the worst of women. Defiant. Independent. Were it not for her beloved younger sisters, she would have sought her freedom long ago. When she refuses to wed an old, wine-soaked English lord, her father bans her to the McKay clan in the Highlands, warning them that she’s a witch.
There is no welcome at the McKay castle—only an aging laird prone to fits of temper who believes that Kali is, in fact, a witch. A sorceress. Here she is little more than a hostage, kept from sight from almost all but Adam McKay, the laird’s son, whose hypnotic green eyes make her long for something forbidden. It’s almost enough to make her abandon all thoughts of escape.

Kali is the only one who can protect her sisters from their father’s greedy machinations. But the longer she remains imprisoned in the McKay tower, the more Kali and Adam realize there are other forces at play. They’re both pieces in a silent, terrible game that could destroy everyone they’ve ever loved…including each other.
