Young adults, ages 12 to 18 are invited to sign up for the 2019 summer Reading Program.  The Bruins autographed jersey incentive is part of a series of prizes that the Boston Bruins organization offers as part of its When You Read, You Score program.  To be eligible to win the jersey, participants  must register at the library, then read two books in addition to any required by their schools.  One of the books must be about space, in keeping with the Universe of Stories summer reading theme.
