More traditional (so far) than other Murakami I've read. No magical realism yet. Our narrator (male) is in love with Sumire, an aspiring novelist. She's in love with an older woman (Miu) for whom she works. Miu likes Sumire, but is not physically attracted to her. Miu and Sumire on a work trip end up on a small Greek island where Sumire, after an awkward attempt at sex with Miu, goes missing.
