In the aftermath of the Boston Marathon bombings, there have been countless stories of good triumphing over evil. The latest comes to us in an e-mail from the south of France, where 114 bombing survivors, family members, and first responders are enjoying an all-expenses-paid cruise sponsored by Boston-based Vantage Deluxe World Travel. (During the 11-day trip, the boat will pass through the Saone and Rhone river valleys, with port calls at Avignon, Chateauneuf-du-Pape, Arle, Viviers, and other locations in Provence.) One of those on the trip is James "Bim" Costello, who suffered such serious burns in the blast that he needed pig skin grafts on most of his right arm and right leg. He's doing better now. We know because he posted this on Facebook: "As you all know, April 15th was one of the worst days of my life, suffering not only physical injuries of my own but the emotional difficulties when I learned about my friends. I soon wondered why and for what reason this had happened. A couple weeks later I was transferred to Spaulding Hospital, where I was able to see my friends starting to heal, but still wondered what good could come from this tragedy. A few days later I saw a nurse in passing, this would turn out to be Krista D'Agostino, who had shared a few mutual friends, but we had never crossed paths before. After sharing a handful of conversations I realized not only how beautiful she was but also what a kind heart she had. I somehow convinced her to attend a benefit with me, which turned into a few dates, which turned into a few inseparable months. I now realized why I was involved in the tragedy, it was to meet my best friend, and the love of my life. Eights months later I'm happy to announce that we will spend the rest of our lives together. . . . We got engaged last night in the middle of the beautiful French city Lyon!!!"
