Cool realism and fantasy intertwine in the story of Sumire and Miu. One is a young, naive, and romantic aspiring writer, while the other is a successful businesswoman, seventeen years her senior. Miu is indifferent to the young woman's desires, who calls her "sweet Sputnik." During a journey through France and Italy to a small Greek island, Sumire suddenly disappears—leaving no trace of her fate. A young teacher, who loves the enchanting Sumire, discovers records of bizarre incidents and stories within stories that also reveal a secret about Miu in Switzerland. With Haruki Murakami's new novel "Sputnik Sweetheart," we find ourselves at the edges of reality, but even as people orbit separately, lonely like a Sputnik, there is still another side to life.
