Perfect strangers : friendship, strength, and recovery after Boston's worst day
(Book)

"In the chaos of the minutes that followed, three people would enter Roseann's life and change it forever. The first was Shores Salter, a college student who, when the bomb went off, instinctively ran into the smoke while his friends ran away. He found Roseann lying on the sidewalk and, using a belt as a tourniquet, literally saved her life that day. Then, Boston police officer Shana Cottone arrived on the scene and began screaming desperately at passing ambulances, all full, before finally commandeering an empty paddy wagon. Just then a giant appeared, in the form of Boston firefighter Mike Materia, who carefully lifted her into the fetid paddy wagon. He climbed in and held her burned hand all the way to the hospital. Since that day, he hasn't left her side, and today they are planning their life together."--Amazon.com.
