“Defending Jacob,” by Boston author William Landay, has been selected for this year’s Abington Reads program. As part of the library-sponsored program, residents are encouraged to all read the same book and take part in events related to it. This year’s program will conclude with visits from Landay, a former assistant district attorney, at the library and Abington High School on March 24. The library also has planned a forensic science program for teens Saturday, a discussion of the book with library director Deborah Grimmett on March 20, and showings of movies with themes similar to the book. In an interview, Grimmett estimated that 250 to 300 people participated last year, the first year of the program. “I would expect the same this year, if not maybe more,” Grimmett said. Last year’s selection was “Dark Tide,” a nonfiction account of Boston’s Molassess Flood of 1919.
