I really enjoyed the first two-thirds of the book, where aspiring writer Jessica and newspaper editor Philip, having met once in person, are exchanging letters on philosophy and worldviews (not usually my thing, but it was entertaining), getting to know each other, and falling in love. But it all falls apart in the last third, where the characters' reactions to the conflict feel wrong, as does the resolution. Your mileage may vary.
This epistolary novel may appeal, if you are interested either in the mind of its author (Paul Elmer More) or in currents and controversies involving religion, philosophy, and social work around the time of its publication (1904). Apart from the letters written when the two lovers were at their most harmonious, I found the story quite enthralling.
