A Question for the Ages by Angeline Fortin

She lost faith in the person she loved most
Lady Piper Brudenall hoped, prayed, and pleaded for her brother to return to London and rescue her from the marriage her mother arranged for her to a despicable nobleman. Heartbroken by her brother’s apparent abandonment but with nowhere left to turn, Piper knew she had no one left to trust. No one to count on. No choice but to save herself. Leaving behind life as she knew it, she ran away from it all. Living right under their noses. Fearing what would become of her if she were ever discovered.

He found love in the most unexpected place
Connor MacKintosh relishes the chance to take control of the Marquis of Aylesbury’s estate, Dinton Grange, while his sister and her new husband were on their honeymoon. Getting his hands dirty evolves into a far more fascinating undertaking when he encounters a bonny lass with a smile potent enough to leave a man weak in the knees. As taken as he is by her, Connor realizes the mysterious woman is running from something, or someone. Unfortunately, he can be of no help to her if she persists in running from him.
Wariness of strangers has kept Piper’s presence at the Grange a secret for more than two years. However, while distrust hasn’t entirely guaranteed security… it has ensured loneliness. When Connor comes along offering a friendly ear, a helping hand, and something more unexpected, she’s torn between her head and her heart. One knows she’d be a fool to put her faith in another man. The other promises that he is a man like no other.

As Piper’s past threatens to catch up with her, Connor will do anything he can to keep her safe. Whether she will trust him with her life and her heart…
That’s a question for the ages.
