Camille Fontaine has always loved butterflies, and they in turn appear to mysteriously be attracted to her. A sheltered, naive, affluent young woman, she finds herself seeking a higher purpose for her life. As the daughter of the Deputy Ambassador to France, her parents wish to marry her to someone of French nobility, something she hopes to avoid.

Against the backdrop of the 1904 St. Louis World's Fair is the wonderment of new inventions, the thrill of meeting people from all over the world, and of course, an observation wheel, a carousel, and a charming, handsome man who brings out emotions Camille never knew she had. She will learn secrets about her family, including a cousin she never knew existed. From this setting, she will begin a journey that leads her to God and to the love of her life, amidst a whirlwind of danger and heartache. This pathway is filled with moments of happiness and tenderness, but also obstacles such as a political boss, rival street gangs, opposition from her own family, and some painful soul-searching. At the heart of all this, is Dr. Cameron Forrester, a dashing physician who has demons of his own which he must battle.

Can faith conquer these barriers? Can love win against such odds as she will face? Are the butterflies God's message to her and are they leading her to her destiny? Only heaven holds the answers to these questions. Through all this, Camille will discover the true meaning of the phrase, "Butterflies are heaven-sent kisses of an angel."
