Refusing to settle for anything less than a romantic relationship that pleases God, Faith O'Connor steels her heart against her desire for the roguish Collin McGuire. But when Collin tries to win her sister Charity's hand, Faith isn't sure she can handle the jealousy she feels. To further complicate matters, Faith finds herself the object of Collin's affections, even as he is courting her sister. The Great War is raging overseas, and a smaller war is brewing in the O'Connor household.
Full of passion, romance, rivalry, and betrayal, A Passion Most Pure will captivate readers from the first page. Book 1 of the Daughters of Boston series.
