To My Scot, With Love by Lizzie C Koz

She’s two-and-thirty, a mother of three—and has never been kissed. Lydia Jennings, Lady Bentley, has spent over a decade in a contractual marriage, fulfilling her duties as a countess and mother. But with her obligations behind her and her children growing up, she’s ready to follow her heart. One man has always tempted her—a big, broad Scotsman with a brogue that sets her blood aflame.
He’s a groom in the stables—and a pathetic, pining Scotsman. From the moment Malcolm Campbell laid eyes on the bonnie Lady Bentley, he was lost. Every exchange, every fleeting glance, has only granted her greater claim over his heart— despite knowing he has no business yearning for a countess. Until she arrives at his door in the middle of the night, turning him from a hopeless romantic…into a hopeful one.

Love letters and sizzling passion unfold. They thought their class differences and her marriage would be their greatest challenge… but as Lydia and Malcolm finally give in to what they’ve both craved, new dangers arise, threatening to rip their love away before it’s had a chance to take root.
