Seduced by the Highlander’s Kiss by Kenna Kendrick

“We can tell nay one of what has passed between us. If yer brother finds out, he’ll kill me.”
Étaín Stuart had committed the ultimate sin – confessing her love to a rake. And by heavens, it went badly.Perhaps it was the ten-year age gap… or the fact that he was her brother’s closest friend. Not only did he break her heart, he then vanished for five long years.
Unfortunately for Étaín, now he’s back: older, more handsome than ever and set on staying away from her as though she were the plague donned in silk.
Bhaltair MacThomas is bad news. A rogue and a half, with enemies chasing him and harboring a heart of ice. He had done everything he could to push Étaín away, but he had done so for her sake. She’s always been off limits and hell, he knows it! But when they meet again, it is a hard pill for Bhaltair to swallow: his feelings for her are still there and grew even stronger during his years of captivity.
He knows he is the worst thing that can happen to her… yet how can he restrain the yearnings of his heart?

The clock is ticking, but the real question is: who will strike first and ultimately drive them apart for good: Étaín’s brother or Bhaltair’s enemies?
Her forbidden kiss was a raging fire, ravishing its way into his heart…
