Disappointing . A thoroughly self-indulgent narrator abandons her family on a whim and ventures out (on her husband's dime?) to "discover herself" and experience the kinds of things her priviledged, sheltered life never offered her. The novel is nicely crafted, but the character is shallow and cloying--sadly, I think we're supposed to support her. I kept hoping she'd return home to an empty house.
Output:
NEG
