Brandnew_SOPHIE'S WORLD by Jostein Gaarder

One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: ”Who are you?” and ”Where does the world come from?” From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village
Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning―but the truth turns out to be far more complicated than she could have imagined
Next, imagine a fantasy novel--something like a modern-day version of Through the Looking Glass
[A] tour de force
