She's found the love of her life.

Unfortunately, he loves her sister.

As World War I rages across the Atlantic in 1916, a smaller war is brewing in Boston. Faith O'Connor finds herself drawn to an Irish rogue who is anything but right for her. Collin McGuire is brash, cocky, and from the wrong side of the tracks, not to mention forbidden by her father. And then there's the small matter that he is secretly courting her younger sister. But when Collin's affections shift, it threatens to tear her proper Boston family apart.
