Once Upon a Wardrobe by Patti Callahan

Megs Devonshire sets out to fulfill her younger brother George's last wish by uncovering the truth behind his favorite story.  The answer provides hope and healing and a magical journey for anyone whose life has ever been changed by a book.
1950:  Margaret Devonshire (Megs) is a seventeen-year-old student of mathematics and physics at Oxford University. When her beloved eight-year-old brother asks Megs if Narnia is real, logical Megs tells him it's just a book for children, and  certainly  not true. Homebound due to his illness, and remaining fixated on his favorite books, George presses her to ask the author of the recently released novel  The Lion, the Witch and the Wardrobe  a question: "Where did Narnia come from?"
Despite her fear about approaching the famous author, who is a professor at her school, Megs soon finds herself taking tea with C.S. Lewis and his own brother Warnie, begging them for answers.
Rather than directly telling her where Narnia came from, Lewis encourages Megs to form her own conclusion as he slowly tells her the little-known stories from his own life that led to his inspiration. As she takes these stories home to George, the little boy travels farther in his imagination than he ever could in real life.
Lewis's answers will reveal to Megs and her family many truths that science and math cannot, and the gift she thought she was giving to her brother-the story behind Narnia-turns out to be his gift to her, instead: hope.
