In [Exiles of the Stars,] the sequel to Moon of Three Rings, [Andre Norton] continues with the story of Krip Vorlund, a Free Trader in some future eon, who through shape-changing entered into the body of a wild animal and then, being unable ever again to regain his original form, was forced to claim as his own the body of a Thassa named Maquad. As in the first book, the Thassa Moon Singer Maelen is integrally bound to Krip although she no longer wears the guise of a woman, having been condemned by her people to take the body of her animal-friend Vors when her own body was broken and dying…. The story is told in the first person by Maelen and Krip in alternating though not ordered sequential chapters; and though the final explanations for the motivations of the four ancient crowned beings who seek to control the life force of the [Free Trader ship] Lydis' crew remain a bit nebulous, the fast pace of the story and the development of the two major characters carries even the literal-minded reader past the stage of mundane questioning to enjoyment.

[Shadow Hawk] will receive a warm welcome, although this is not in [Norton's] popular science-fiction style. Here we have a convincing reconstruction of an aspect of Ancient Egypt in about 2000 B.C.… Although the book is not easy reading and has a surfeit of names, it nevertheless presents a very forceful picture of life in Egypt at that time. The military and other actions are handled with great skill and excitement, and the main characters are well drawn. (p. 253)

A new departure by an author better known as a writer of science fiction. [In Bertie and May] Andre Norton tells of her mother's childhood in Ohio nearly one hundred years ago. The story is founded on her mother's own written account and is supplemented by the many anecdotes she told to her children and grandchildren before her death at 95. The result is a convincing picture of two little sisters and the way of life in the 1870's. It was an unsettled life, for the sisters' father was a miller at a time when his kind of milling was almost outdated, but loyalty and family unity surmounted the hardships.

The adult reader inevitably compares this chronicle with the Laura Wilder books, although the background is not one of pioneer life. Andre Norton's is a much slighter work and the reader's sympathies are not as totally involved with Bertie and May as with Laura. Nevertheless, this is an engaging picture of a real family in a rural township in America and it has humour and warmth. (p. 308)

In some ways Mrs. Norton's [Postmarked the Stars] is a complicated game of hide-and-seek in outer space, first on board the free-trading spaceship, Solar Queen, eventually on Trewsworld, a planet whose constitutional and industrial status is being undermined by a corrupt scientific organisation…. On Trewsworld an exhilarating sequence of discoveries and escapes keeps the reader on tenterhooks for what seems a very long time. Mrs. Norton's detail is, as always, convincing, and her extension of the possibilities of mutation in animal strains carries fascinating but forbidding implications for the human race. (p. 321)
