Sputnik Sweetheart — Haruki Murakami

Part romance, part detective story, Sputnik Sweetheart tells the story of a tangled triangle of uniquely unrequited love.

Now with a new introduction from the author.

K is madly in love with his best friend, Sumire, but her devotion to a writerly life precludes her from any personal commitments. At least, that is, until she meets an older woman to whom she finds herself irresistibly drawn. When Sumire disappears from an island off the coast of Greece, K is solicited to join the search party -- and finds himself drawn back into her world and beset by ominous visions. Subtle and haunting, Sputnik Sweetheart is a profound meditation on human longing.
