An Unsuitable Lady for a Lord — Cathleen Ross

Lord Aaron Lyle has one hell of a choice: a bankrupt dukedom, or marriage to some simpering society miss so his spendthrift father can get his hands on her huge dowry. He won't do it. He has a reputation to maintain, and besides, he'd rather run naked through the streets of London than marry anyone at all. Surely, there must be a third option.

Then Lady Crystal Wilding walks into his life, a bluestocking, full of subversive thoughts, who hates the notion of marriage even more than he does. He is intrigued...and suddenly he has an idea. He invites the totally unsuitable lady home on the pretext of presenting her as a possible match...but in truth, Aaron has something far more pleasurable in mind. For her part, Lady Crystal has her own reasons for going along with his harebrained scheme.

Imagine their shock when his highly proper family loves her and starts planning the wedding. Good lord. Now what?
