 
In the first book on this iconic event, 4:09:43, Hal Higdon, a        contributing editor at Runner’s World, tells the tale of the Boston        Marathon bombings. The book’s title refers to the numbers on the        finish-line clock when the first bomb exploded.     
       In 4:09:43, Higdon views Boston 2013 through the eyes of those        running the race. You will meet George, a runner from Athens, birthplace        of the modern marathon, who at sunrise joins the eerie march of silent        runners, all aimed at their appointments in Hopkinton, where the        marathon starts. You will meet Michele, who at age 2 helped her mother        hand water to runners, who first ran the marathon while a student at        Wellesley College, and who decided to run Boston again mainly because        her daughter Shannon was now a student at Boston University. You will        meet Tracy, caught on Boylston Street between the two explosions,        running for her life. You will meet Heather, a Canadian, who limped into        the Medical Tent with bloody socks from blisters, soon to realize that        worse things exist than losing a toenail.     
       In what may be a first, Hal Higdon used social media in writing 4:09:43.        Sunday, not yet expecting what might happen the next day, Higdon posted        a good-luck message on his popular Facebook page. “Perfect weather,” the        author predicted. “A ‘no-excuses’ day.” Within minutes, runners in        Boston responded. Neil suggested that he was “chilling before the        carb-a-thon continues.” Christy boasted from her hotel room: “Bring it!”     
       Then, the explosions on Monday! Like all runners, Higdon wondered        whether marathoners would ever feel safe again. Beginning Tuesday,        runners told him. They began blogging on the Internet, posting to his        Facebook page, offering links to their stories, so very similar, but        also so very different. Over the next several hours, days, and weeks,        Higdon collected the tales of nearly 75 runners who were there, whose        lives forever would be shadowed by the bombs on Boylston Street.     
       In 4:09:43, Higdon presents these stories, condensing and        integrating them into a smooth-flowing narrative that begins with        runners boarding the buses at Boston Common, continues with the wait at        the Athletes’ Village in Hopkinton, and flows through eight separate        towns. The story does not end until the 23,000 participants encounter        the terror on Boylston Street. “These are not 75 separate stories,” says        Higdon. “This is one story told as it might have been by a single runner        with 75 pairs of eyes.”     
       One warning about reading 4:09:43: You will cry. But you will        laugh, too, because for most of those who covered the 26 miles 385 yards        from Hopkinton to Boylston Street, this was a joyous journey, albeit one        that ended in tragedy. This is a book as much about the race and the        runners in the race as it is about a terrorist attack. In future years        as people look back on the Boston Marathon bombings, 4:09:43 will        be the book that everyone will need to have read.
