An Uncommon Governess(1998)
(The first book in the North's Irregulars series)
A novel by Monique Ellis
Determined not to marry, Lady Amelia runs away from home. Disguising herself as bespectacled Abigail Sparrow, she accepts a position as governess. Her employer, Valentine North, had always sworn he would remain unattached--despite the fact that he'd been given charge of two wards. But soon, Val is not only in danger of tarnishing his reputation as a freewheeling bachelor, but also of losing his heart to Amelia.
