she visits her maternal grandparents in An Acceptable Time. Maddox's equally fictional first novel, Once More United, is said to have been published in 1865. Vespugia Vespugia is the same fictional country that L'Engle's character Vicky Austin later visits in Troubling a Star. L'Engle explains in Walking on Water that Vespugia is "set in the middle of what used to be called Patagonia, a sizeable area along what are now the boundaries of Chile and Argentina". L'Engle's husband, Hugh Franklin, is credited with having named Vespugia. Series This is the third book of the Time Quintet, preceded by, in publication order, A Wrinkle in Time (1962) and A Wind in the Door (1973). However, this was not the chronological order. Though Many Waters was written and published later than A Swiftly Tilting Planet, it takes place earlier with respect to the characters. The last book in the Quintet, An Acceptable Time, takes place a generation after A Swiftly Tilting Planet, and is part of the Polly O'Keefe series of books. The larger "Murry-O'Keefe" series (the Time Quintet plus the books of Poly/Polly O'Keefe) contains three novels between A Swiftly Tilting Planet and An Acceptable Time in terms of character chronology. These are The Arm of the Starfish, Dragons in the Waters, and A House Like a Lotus. Audio adaptation In January 2012, an audio CD version narrated by actress Jennifer Ehle was released. Reception At the time of the book's publication, Kirkus Reviews said, "L'Engle's irksomely superior Murry family reassembles here for Thanksgiving dinner... The idea, according to the unicorn, is for Charles to influence a Might-Have-Been which determines whether Branzillo is descended from the good or the bad line, and thus (?!) whether he will or will not start a nuclear war--a shaky if not asinine premise on which to build an earth-tilting adventure." In a 2012 essay for Tor.com, American author and critic Mari Ness wrote, "A Swiftly Tilting Planet is simultaneously one of L'Engle's most beautiful and poetic novels, filled with joy and despair, and also one of her most frustrating, a book that both celebrates her earlier books while completely contradicting some of their most important and fiercely argued ethical points. I find myself dazzled and irritated." Awards and honors In its first paperback edition, A Swiftly Tilting Planet won a National Book Award in category Children's Books (paperback).
