The Nearness of You (The Thorntons #1)
Iris Morland

The problem?
He’s Harrison Thornton, the oldest son of the illustrious Thornton family. His family would never accept a woman like Sara, a woman who grew up on the wrong side of the tracks. She tries to ignore the whispers of her past, but she soon realizes secrets can never stay hidden for long.
Especially from the man claiming her wounded heart.
Growing up in the rich and powerful Thornton family, Harrison has lived a charmed life. A renowned physician, the last thing he expects is to desire the mother of one of his patients. Sara is beautiful and intelligent, and she’s completely devoted to her son, something that only deepens his attraction to her.
He doesn't want a single night of passion, though: he wants forever. Yet there are forces at work and people determined to tear them apart. Even Sara turns from him, certain she's unworthy. Harrison refuses to let Sara slip away, and soon, he’s fighting the greatest battle of all.
The battle to win the heart of the woman he loves.
