DOMINIC MARTELL was born in the United States and has spent most of his life there, but he has lived and traveled extensively in Latin America, Europe and the Middle East. He has worked as a teacher and a translator. The first three novels featuring repentant ex-terrorist Pascual Rose appeared in the 1990s, chronicling Pascual's quest for atonement in the chaotic early years of the post-Cold War period. A quarter of a century later, in the transformed landscape of the even more chaotic post-9/11 digitally connected world, Martell began to wonder what had become of Pascual and decided to bring him out of retirement. Kill Chain is the first of Pascual's 21st-century misadventures.
