Query: Love endures

Robert Nathan, the author of many dozens of short novels, usually taking the form of urban fables (sometimes with animals as the characters), was mainly concerned with one or more of the following at any given time: patriotism, team work, having faith in what you're doing, opposition to authoritarianism, and most of all, the enduring quality of love.In this novel a down-and-out artist (Eben Adams) in NYC meets a young girl named Jennie. She seems much older to Eben, as if she came out of a time machine from an earlier period. They fall in love, but mysteriously she insists she can't stay with him. And she vanishes from his life.Or so he thinks. Later in a hurricane off Cape Cod he finds her again; still later he learns that she drowned when she fell off a ship years ago. It's all a very strange lovelorn story of what was once in the past that is lost in current time. Nathan's message is clear, though: love endures.
