When a massive fire breaks out in the middle of a July night, the three women are brought together, and each is forced to reevaluate her priorities and answer the harrowing question: “What—and whom—would you save?”   Eliza Macy, wife to a whaling captain at sea for years on end and mother of three daughters, fights to conceal her financial troubles and keep her feelings for an old flame at bay, all while reckoning with the sincerity of her so-called “progressive” values.   Maria Mitchell, a character based on the real-life female astronomer born and raised on Nantucket, runs the island’s library, the Atheneum, and spends her nights stargazing
