Dawn In My Heart — Ruth Axtell Morren

Called home to Regency London after his brother's death, Tertius Pembroke, Earl of Skylar, must marry quickly and produce an heir. Lady Gillian Edwards seems the ideal bride: young, beautiful and innocent. But Sky is no ideal husband, having returned from the Indies gaunt, ill and plagued by a darkness that he dare not reveal -- even to his betrothed.

Lady Gillian had promised Sky her hand in marriage but cannot give him her heart -- not when she gave it to another man three years ago. Afraid of repudiation, Gillian buries her secret so deep inside herself, no one will ever know -- or so she hopes.

Through lies and deceit, their marriage slowly unravels. Then Sky becomes deathly ill, and his newfound faith offers two virtual strangers a second chance at becoming husband and wife.
