Love on the Coast by Ciara Knight

A fake marriage for these enemies turned lovers will be tested and only trust can save them.

Irish immigrant Edward O’Neal landed in America as a little boy with the promise of a better life but found prejudice and poverty. Poverty that took his entire large family from him. He’s spent the last twenty years hiding his heritage and building his fortune so he’d never go hungry again. But when he discovers that his partner ran away with a prostitute to escape his gambling debts and his empire is crumbling, the last ace in his pocket is his mail-order bride — a woman of pure breeding, with a political family name, high class, and huge dowry.
Cora McKinnie managed to live through the Civil War long enough to see her parents, brothers, and fiancé die and to send her six sisters away to wed. Alone, she makes the arduous journey to San Francisco to marry and start her own loving family. Dreams sour when she discovers her betrothed is dead and his jilted, angry partner despises her for being Irish and the only woman available to marry.
To recover his fortune, Edward must pull off the event of the year with little funds. A nearly impossible task without the help of the distracting, beautiful, thrifty Irish woman with a huge heart.
