Question: Lucy Pevensie is a character in the series of fantasy novels that have sold more than how many copies?

<P0-S0> The cosmological interpretation of quantum mechanics, proposed by Anthony Aguirre and Max Tegmark, is an interpretation of quantum mechanics that applies in the context of eternal cosmological inflation, which arguably predicts an infinite three-dimensional space with infinitely many planets and infinitely many copies of any quantum system. <P0-S1>  According to this interpretation, the wavefunction for a quantum system describes not some imaginary ensemble of possibilities for what the system might be doing, but rather the actual spatial collection of identical copies of the system that exist in our infinite space. <P0-S2>  Its collapse can be avoided. <P0-S3>  Moreover, the quantum uncertainty that you experience simply reflects your inability to self-locate in space, i.e., to know which of your infinitely many copies throughout space is the one having your subjective perceptions. <SEP> <P1-S0> The Chronicles of Narnia is a series of seven fantasy novels by C. S. Lewis. <P1-S1>  It is considered a classic of children's literature and is the author's best-known work, having sold over 100 million copies in 47 languages. <P1-S2>  Written by Lewis, illustrated by Pauline Baynes, and originally published in London between 1950 and 1956, "The Chronicles of Narnia" has been adapted several times, complete or in part, for radio, television, the stage, and film. <SEP> <P2-S0> From Unknown Worlds is an anthology of fantasy fiction short stories edited by John W. Campbell, Jr. and illustrated by Edd Cartier, the first of a number of anthologies drawing their contents from the classic magazine "Unknown" of the 1930s-40s. <P2-S1>  It was first published in magazine format by American company Street & Smith in 1948; the publication was an attempt to determine if there was a market for a revived "Unknown". <P2-S2>  Street & Smith printed 300,000 copies, against the advice of John Campbell, but although it sold better than the original, too many copies were returned for the publisher to be willing to revive the magazine. <P2-S3>  The first British edition was issued by Atlas Publishing in 1952; part of the run was issued in a hardcover binding. <P2-S4>  This edition omitted the story "One Man's Harp." <P2-S5> . <SEP> <P3-S0>  She is the youngest of the four Pevensie children, and the first to find the Wardrobe entrance to Narnia in "The Lion, the Witch and the Wardrobe". <P3-S1>  Of all the Pevensie children, Lucy is the closest to Aslan. <P3-S2>  Also, of all the humans who have visited Narnia, Lucy is perhaps the one that believes in Narnia the most. <P3-S3> Lucy Pevensie is a fictional character in C. S. Lewis's "The Chronicles of Narnia" series. <P3-S4>  She is ultimately crowned Queen Lucy the Valiant, co-ruler of Narnia along with her two brothers and her sister. <P3-S5>  Lucy is the central character of the four siblings in the novels. <P3-S6>  Lucy is a principal character in three of the seven books ("The Lion, the Witch and the Wardrobe", "Prince Caspian", and "The Voyage of the Dawn Treader"), and a minor character in two others ("The Horse and His Boy" and "The Last Battle").
