Hermin, a composer and instructor, leads a secluded life near the Bourbonnais Mountains in France, composing a homage to Schubert. On a bitter January night, this studious peace is broken when his former pupil, Lenny, a piano prodigy, mysteriously knocks at his door. The two men must confront the ghosts of their past, somewhere between musical harmony, erotic tension, and revelation. Wanderer, echoing Schubert's recurring theme, is a novel of rare delicacy, a twilight adagio, a Winterreise, and a subtle ode to German Romanticism.
