"Perhaps it does not matter very much in which order anyone reads them," concluded C. S. Lewis in a letter—now famous among Lewis fans—dated April 23, 1957.
Lewis's correspondent was an 11-year old American boy named Lawrence Krieg who had written suggesting the seven Chronicles of Narnia should be read in their chronological order, with The Magician's Nephew first, rather than in their publication order as was indicated on the covers and the one Lawrence's mother preferred, with The Lion, the Witch and the Wardrobe first.
Lewis initially seemed inclined to possibly accept Lawrence's proposal, though with qualification, writing: "I think I agree with your order for reading the books more than with your mother's." But given his later statement, that perhaps the order did not matter very much, it seems more likely that he was simply being gracious to a young admirer.
What is known is that all during Lewis's lifetime and for seventeen years after his death, the Chronicles kept their original publication order numbers. Then in 1980, these numbers were changed to the chronological order they bear today. Anyone buying a copy of The Lion, the Witch and the Wardrobe now will find a number two on its spine and the following statement inside: "The HarperCollins editions of The Chronicles of Narnia have been renumbered in compliance with the original wishes of the author, C. S. Lewis."
Lewis scholar Peter Schakel finds the use of the word "original" in this claim puzzling and asks: "Does 'original' mean from the time at which The Magician's Nephew was completed? If so, why did Lewis not request the Bodley Head [his publisher] to include this renumbering in the new book, or in The Last Battle the following year, or have Geoffrey Bles [his later publisher] change the order in later reprints of the other books? If it had been a matter of importance to Lewis, surely his publishers would have complied with his wishes, or included the renumbering in the paperback editions that appeared a few years later."
Despite Lewis's kindly words to Lawrence Krieg, Schakel maintains that the order the books are read in "matters a great deal" and argues that the original ordering is preferred by "a number" of Lewis scholars, an understatement that should read "most" or "nearly all."

The Lion, the Witch, and the Wardrobe in my opinion should be read first. Children should enter Narnia for the first time through the wardrobe. The wonder is indeed lost when The Magician's Nephew is read first. Lewis himself wrote that the stories came to him in images and he wrote no more about Narnia after the images stopped. The first image was that of a faun in a snowy woods.
Magic rings were how Digory, Poly, and the witch queen Jadis entered Narnia. In the case of the Pevensie children their entrance into Narnia coincides with Aslan's return and has all the earmarks of his doing.
