A Highlander's Reiver

Captivity was only the beginning...
When a Highland lass is the orphaned charge of an uncle who leads ne'er-do-wells and thieves she has no choice but to stay and steal. No choice because leaving would mean abandoning her little brother. She's told him not to follow her when she's out reiving cattle from other clans. It's just her luck he would choose to follow her on the night she's captured.
Drew MacIntosh never imagined he'd become the guardian of his sister's twin toddlers. He's a fighter. He's not father material. Especially not to bairns as young as these two. And now he's added to his burdens by apprehending a captivating reiver of a lass. One with a burden of her own, it would seem.
How is he supposed to turn the lass over to Rufus so she can pay for her crimes when it would mean her brother would be left in the hands of brigands and cattle raiders?
Life was so much simpler when he was soldiering and fighting.
