The Earl's Ugly Mistress - The Longleigh Chronicles, #8

Lady Flora adores matchmaking, the more challenging the better. So, why not pair the newly blinded Earl of Edgemont with tart-tongued Lucia Stilwell, a homely spinster who will allow no pity for his condition, exactly what he needs. When the clever Lucia shows him a few tricks to deal with his blindness, Edgemont asks her to stay at his estate and teach him more. She accepts, regardless of the scandal it might cause.
All goes well until the earl appears to be regaining his sight. Loving him, Lucia must flee before he sees her face. Will he follow or let her go?
