Road to Paradise — Max Allan Collins

As a young man, Michael Satariano fought Capone's gang in Chicago. Now in comfortable middle-age, he runs a mob casino in Lake Tahoe, with a loving wife, a teenage daughter, and a son earning medals in Vietnam. The year is 1973, and he believes his killing days are behind him. But the bosses have other plans. And when he refuses to do a hit ordered by resurgent godfather Sam Giancana, Michael finds himself framed for murder--and forced to disappear into the government's fledgling Witness Protection Program to keep his loved ones safe.

But there is no escape from the life he left behind. And when history tragically repeats itself, Michael takes to the road once more, with his daughter in tow, to seek vengeance.
