[9] Critics praised the novel for sustaining its length[10][11] and for Shipstead's research[12][13] and intricate novel structure for perfectly interweaving the parallel narratives, despite the time and circumstances separating them.

[2][13] In its starred review, Publishers Weekly wrote, "Shipstead manages to portray both Marian's and Hadley's expanded sense of consciousness as they push the boundaries inscribed around them [...] This is a stunning feat.

"[13] Stephanie Merritt, for The Observer, wrote, "This is a novel that invites the reader to immerse themselves in the sweep of history, the rich and detailed research, and part of the pleasure is being carried along by the narrative through all its digressions and backstories.

"[12] Library Journal wrote that the novel "justifies its length, by its intricately designed plot and by giving its compelling cast of characters room to breathe.

"[11] Ron Charles of The Washington Post called it a "culturally rich story that takes full advantage of its extended length to explore the changing landscape of the 20th century."

However, Charles lamented that the "extraordinary realism of Marian's chapters can make the broad strokes of Hadley's sections feel light in comparison.
