The Human Target Book One

"Christopher Chance has made a living out of being a human target--a man hired to disguise himself as his client to invite would-be assassins to attempt his murder. He's had a remarkable career until his latest case protecting Lex Luthor when things go sideways. An assassination attempt Chance didn't see coming leaves him vulnerable and left trying to solve his own murder, as he has 12 days to discover just who in the DC Universe hated Luthor enough to want him dead by slow-acting poison. And the prime suspects happen to be the Justice League International?"--
