The characters of “Archipelago of the Sun” are only half-aware of where they’re headed; its readers, even less. The final volume of Yoko Tawada’s trilogy concludes the pan-European romp, but offers no neat resolution.

Sixty-five-year-old Tawada, a Tokyo native who lives in Berlin, is praised by critics and fans for her ability to write in both German and Japanese. The trilogy — “Archipelago” and the first two volumes, “Scattered All Over the Earth” and “Suggested in the Stars” — were written in Japanese, with English translations by Margaret Mitsutani.

Archipelago of the Sun, by Yoko Tawada. Translated by Margaret Mitsutani. 256 pages. NEW DIRECTIONS, fiction.
