Glimpses of the Moon

Nick Lansing and Susy Branch are two young and attractive, but penniless New Yorkers. They decide to marry, but realize their chances of happiness are slim without the wealth, taken for granted by their more privileged friends. Nick and Susy agree to separate if either of them encounters a more eligible proposition and set out on a lavish honeymoon in Europe, funded by their wealthier friends. Unexpected feelings and jealous passions ensue, set against a backdrop of exquisite villas, palazzos and chateaus in Europe's glittering 1920s.
A highly enjoyable page-turner, "The Glimpses of the Moon" was Edith Wharton's last completed novel.
