There is at least one good man on Wall Street: Howard Lutnick, CEO of Cantor Fitzgerald. Faced with devastation and horror on 9/11 losing 658 of 1000 NY employees in the attack, few would've survived--much less thrived and taken care of the victim's families. 'On Top of the World' is the riveting book profiling his courage, his absolute will and determination, and his transformation as a human being in the process. Inspirational! Life-changing true life stories are always important reads.
