Celebrated New York-based performance poet Hala Alyan reads from and discusses her debut novel, “Salt Houses” (Houghton Mifflin). The book tells the intergenerational story of a Palestinian family that gets uprooted during the Six-Day War of 1967 and again during Saddam Hussein’s 1990 invasion of Kuwait. Ambitious in scope and told with Alyan’s lyricism, “Salt Houses” is a much-anticipated debut.
