My Lady, My Lord by Katherine Ashe

Book #1 in a new series of historical romances... with a twist.

The Bluestocking
Lady Corinna Mowbray has three passions: excellent books, intelligent conversation, and disdaining the libertine Earl of Chance.

The Rake
Lord Ian Chance has three pleasures: beautiful women, fast horses, and tormenting high-and-mighty Corinna Mowbray.

Neighbors for years, they've been at each other's throats since they can remember. But when a twist of fate forces them to trade lives, how long will it be before they discover they cannot live without each other?
