The Roman of the North

Even the Roman Legion cannot keep Antonius from his heart's desire . . .
They are on opposite sides of a war, separated by a wall. He's her most hated enemy as a soldier of Rome, but nothing can stop his desire. Who is this northern beauty who stole his breath and his heart the moment he first saw her?
Antonius, a Roman soldier assigned to the Northern Isles, is cold, tired, and stuck in his Roman camp south of Antoine's Wall. Since the inception of the treaty between Rome and the barbaric Caledonii, the soldiers have done little more than boring and demeaning grunt work.
How is this the glory of Rome?
Antonius prides himself on honor, and his inner turmoil is tested when the Prefect sends Antonius and several other soldiers on a scouting mission north of the wall to break a good-faith treaty. He's caught by three Caledoniis - one of whom holds a spear to his neck. Only, she's not the one who has Antonius's attention.
It's the other woman with her - the curvaceous, red-haired woman with wild curls and the sensibility to question Antonius instead of kill him - who has his full attention. Muireall.
Though it's been a long while since Antonius has been with a woman, surely his stark and brutal attraction is driven from need and not something more.
Antonius is wrong, so wrong. His desire for this enticing Caledonii lass urges him to help her people repel an attack by the treacherous Romans, his own people, in his quest to stay with Muireall. She might be his enemy and best friend of the chieftain's daughter, but he wants her nonetheless. And he will have her.
But the Romans are devious and resolute, and when a surprise attack goes awry, his vow to protect the Caledonii and safeguard Muireall's life are on the line.
A battle is brewing between the Romans and the Celts. Can Antonius walk that line into his future, or will his obligations to the Romans destroy everything he's grown to love?
