The Viscount in her Bedroom by Gayle Callen

Louisa Shelby’s carefree life of elegant balls and beautiful gowns ended when her father died, leaving her penniless. With no hope of securing a proper marriage, she accepts a position as a companion to an elderly viscountess. But temptation in a most unexpected guise awaits Louisa in the dowager’s home…
Once, Simon Wade was London’s most eligible bachelor, but a tragic accident forced him into seclusion, away from prying eyes and questions. While he yearns to hold and kiss the enchanting Louisa, he will accept no woman’s pity.
Louisa’s only chance at happiness may rest in her ability to convince the stubborn viscount that her passion is real…and her love is true.
