You’re invited to the Library on Saturday, March 12 at 12:30 to hear author John Morris discuss his book Alone at Sea: Gloucester in the Age of the Dorymen 1623-1939. The talk will focus on the time when Cape Ann fishermen were faced with unseen enemies in German U-boats prowling the area. A question/answer period, book signing, and refreshments will follow. Books will be available for purchase at the Library. Please contact the Library to register for this event, which is sponsored by the Hanson Public Library Foundation.
