The Irish Bride. Central City Brides, #3

Erin O'Toole is no stranger to violence. Growing up surrounded by one of the most powerful gangs in New York, Erin learned how to survive. But when her little brother is killed in a gang war, Erin swears she'll never be part of her father's world. Desperate to escape the pain of her loss and a future she doesn't want, she risks everything to become a mail-order bride. After years of being on the wrong side of justice, Henry Jacobs has made things right.
Now he is a peaceful blacksmith in Central City in the Colorado Territory and all he wants is a wife and children of his own. One look at Erin, and Henry falls for his feisty new bride. But Henry has secrets that could tear their marriage apart. When a man from Henry's past threatens his new life, Henry finds he has no choice but to become a man she'll hate in order to save the woman he loves.
