Assassins Anonymous

Mark, once the world’s deadliest assassin, has given up killing and joined a support group for reformed hitmen. But when he’s attacked by mysterious enemies, he’s forced to go on the run across the globe—New York to Singapore to London—while trying to uncover who’s hunting him. The catch? He must survive without breaking his vow of nonviolence, proving that for an ex-assassin, living peacefully can be the hardest mission of all.
