Florida, a collectoin that show us the maturation of a writer

The stories are not "dated" in Lauren Groff's collection, Florida, but it appears to me that some of the stories int the middle of the book are earlier works. I see this on two levels: First, they have some of the themes we see in Groff stories that I know to be recent (based on their appearances in the New Yorker) - e.g., woman in distress and suffering or about to suffer because of her mistake in judgement, female protagonists w/ strong personalities and opinions - so strong that they tend to alienate friends and even family, and portraits of a neighborhood, a real sense of place. But I ID some as earlier because they're less complex, their endings are abrupt rather than evocative, provocative, or open. A second clue as to story dates has to do w/ topical referents. For ex., one of the best of the "early" stories is Salvador, about an a attractive 30-something woman who's committed to providing full-time care to her mother, but, with help from her sisters (who feel some guilt that they cannot devote the same time to their mother) she takes a month's vacation every year in an exotic locale, i this case an eponymous city in Brazil. A clue as to date of composition: The woman, while on vacation, writes letters to her mother and sisters. Hasn't happened since about 1998, right? In this story, the woman uses her month's vacation to pick up various men - businessman, local artisans, et al - and have sex; this seems an extraordinarily risky behavior, which I expected would cause the protagonist great harm, but I was wrong about that. She does, however, have a close brush w/ violence, but not because of her sexual abundance (basically, caught in a torrential rain and rescued by someone who menaces her through the night). Though the story is fine and unusual, it seemed to me that there were too many red herrings (she sees a young girl seemingly held captive in a grocery store, but nothing comes of this, at least not directly), and the story ends without the protagonist changed or transformed in any significant way. Compare this with the first 3 pieces in the collection - in which Groff shows her characters - two women, one man - transformed by traumatic experience. It's great that these works come together in a single volume, as they show us the education and maturation of a writer; info on dates of publication, though, would be a plus.
