A Romance of Two Worlds starts with a young heroine, in first person, telling her story of a debilitating illness that includes depression and thoughts of suicide. Her doctor is unable to help her and sends her off on a holiday where she meets a mystical character by the name of Raffello Cellini, a famous Italian artist. Cellini offers her a strange potion which immediately puts her into a tranquil slumber, in which she experiences divine visions. Upon wakening, she craves more. Later, she meets her unnamed guardian angel, who whisks her through infinite solar systems faster than a shooting star while human spirits fly by like gossamer silk. He shares the truth of religion and the secret of human destiny, but still she longs for more. She comes to understand God as pure light and pure love, but it is not enough that she should see and hear these things from the touch of an angel. She wants to master this ability on her own and seeks a oneness with God through a series of meditative disciplines while locked away in a monastery.
