Lance Olsen and John Domini have followed each other’s work for years, sharing an attraction to the edges of the fictional enterprise, to experiment and risk. Olsen has many works of fiction and non-fiction, and his awards include the Guggenheim. Domini too has published widely, in all genres, and won an NEA Fellowship. Both have spent extended time abroad, Olsen in Germany, Domini in Italy. Not till now, however, did they share new titles with similar core concern— namely, a European city going through a radical change. In Domini’s case, in his novel The Color Inside a Melon, this was contemporary Naples, over a single hectic week. Olsen’s latest, My Red Heaven, considers a June day in Berlin, in 1927.
