Larry DiCara, former member of the Boston City Council, will speak about his memoir “Turmoil and Transition in Boston,” which gives his perspective on the upheaval that shook the city when a federal court ordered the schools to desegregate in 1974. It is also the story of his family, his campaigns for office, and the changes that have transformed Boston since the 1950s. The event will be at the Honan Allston Library, 380 Harvard Street, Allston on Wednesday, April 9 from 6 to 8 PM, with an introduction by State Representative Kevin Honan.
