The Brides of North Barrows is a series of Regency romance novellas. There will ultimately be four stories in all.
This fictional realm connects some of the other worlds in the Regency era. Alexander, the hero of A Duke By Any Other Name, for example, is the Duke of Inverfyre, which you’ll recognize as the Highland holding in the Ravensmuir world held by the Armstrong family (who we first encounter in The Scoundrel.)
Alexander also lives at Airdfinnan, which is the home of Angus MacGillivray in The Beauty in the Bride Quest world. Clearly, these worlds have been connected at some point between the Middle Ages and the Regency. There’s a story in that!
Finally, Alexander has a seed from the vine that grows at Airdfinnan in The Beauty, which has become legendary. It sprouts in A Duke By Any Other Name, making a believer of Alexander.
