La noche del oráculo por Paul Auster

De momento solo tenemos la sinopsis en inglés.

A novelist recovers from an accident. He begins to write again, after buying a blue portugese notebook. The words flow, but at some point, strange things begin to happen: his beloved wife behaves strangely, fiction and reality get mixed up, and what about this strange stationary shop where he bought the notebook? It disappears over night.
