The Marquess of Secrets by Karyn Gerrard

A secret life
For years Harrison Hornsby, Marquess of Tennington, heir to the Duke of Gransford, has been a scandalous rake. Unbeknownst to all he’d been leading an entirely different and secret life as physician to the poor. Though his younger brothers held out for true love, as the heir, Harrison feels he doesn’t have that luxury. The time has come to marry an appropriate bride. One who in society’s eyes is worthy to become a duchess. But fate has other plans.

A damaged woman
Life for Lydia Chesterton has not been kind. Once a respected nurse at a London hospital, she is alone and homeless due to disastrous decisions with regard to love and trust. Living on the streets and deathly ill, Lydia finds temporary sanctuary with Harrison. Her rescuer is hard to resist especially when he proposes a trade of secrets. With her dangerous past threatening her future, and Harrison bound by duty, a lasting love appears to be out of reach…unless they toss aside all obstacles and risk their hearts.
