Troublesome Temptations (Mpreg Regency Romance). Omega House, #1

Love doesn't factor into the life of an Omega. Raised in England's premier Omega House, Hawthorne Fuller faces only one possible future: wed a nobleman and bear his heirs. It's a fate he never questions, despite his misgivings when he signs a marriage contract binding him to an earl he's never met. Attacked by highwaymen on the way to his wedding, Thorn is forced to take shelter with a wholly unsuitable man.
A man who arouses a maelstrom of feelings Thorne has never experienced in his sheltered life. With his body, and his heart, awakened to forbidden desire, Thorne discovers the security of a noble marriage holds little appeal. But the future may not be his to decide. Even the best kept secrets can refuse to stay buried. It has been years since Wil Berecroft sought anything beyond the simple living his alehouse affords him.
He isn't looking for an omega, certainly not for one betrothed to the despised Earl of Maebard. Discovering Thorne hiding in his barn threatens to set Wil's entire life on end. The secrets Wil keeps are in danger of resurfacing, but he can't deny his attraction to Thorne. Torn between the omega and the life he's built, Wil can't swear he'll make the right choice...but no matter what he chooses nothing will ever be the same.
A Regency-flavored m/m romance, featuring instalove, mpreg, and a hearty helping of spice.
