Left widowed and penniless after a loveless arranged marriage, Jillian reluctantly accepts the job of "refining" a Scottish Highlander who's inherited an English title. The man infuriates and intrigues her, as well as shakes her resolve to never again let a man close. Ian MacLeod never wanted to come to England, but his clan needs the profits he can gain by claiming his inherited English lands. When he meets the very proper Lady Jillian Newburn, he's fascinated by what he suspects is a warm heart and fiery passion underneath her icy demeanor.

Jamie MacLeod is the most annoying male Mari has ever had the misfortune to meet. It certainly doesn't help that he's devilishly handsome and as tall and broad as a tree. No matter what Mari's new brother-in-law seems to think, she doesn't need the hulking, kilted Highlander to hover over her. Jamie longs to return to the Highlands. Chaperoning his new sister-in-law's little sister in London sounds about as pleasant as being strangled by one of those infernal cravats the English insist on wearing, especially since the young woman seems determined to slip away from his protective duty.

Abigail Townsend longs for the type of excitement she reads about in her beloved books. She knows she won't find anything remotely resembling an adventure at any of the stuffy events of the ton, so she sets out to find one of her own. Shane MacLeod is a man of many talents and titles. He's a Highlander, a ship captain, and a member of the Knights Templar. When he sets out to sea bound for an important meeting of Templars, he realizes too late the lad his cook hired is a girl. And when that girl turns out to be an earl's daughter, he soon adds "husband" to his list of titles.

A victim of a madman who wants revenge on her family, Fiona MacLeod is kidnapped and committed to the Dublin Lunatic Asylum. Her only bit of good luck is that the asylum's overcrowded and she's assigned a room in a nearby castle. She knows the more she tries to convince her captors of the plot against her family, the more insane she sounds, but she finds a spark of hope in the young earl of the castle.

Surrounded by Highlander brothers and cousins, Shauna MacLeod is used to big and burly men thinking they're in charge. The visiting American ship captain is a breath of fresh air and a welcome distraction from her daily duties at the MacLeod dock office, even if his past seems to hold more secrets than the sea. Captain Robert Henderson has his share of complications waiting for him when he returns to New Orleans, so he knows he needs to stay away from Shauna until he's managed to uncomplicate his life, no matter how tempting she is. 

Bridget MacLeod needs some space from her well-intentioned but overbearing family who've been crowding around her since her husband's death. How can she keep her late husband's secret and explain to them that her arranged marriage was pleasant but passionless, that she lost a friend but not a lover? Seeking a change of scenery, she arrives in Arisaig only to find she has no place to stay, unless she accepts the offer from a family friend.
