Shoot the Moon — Joseph T. Klempner

All his life he has stayed in the comfort zone: never taking any chances, never breaking any rules. Now, Michael Goodman, bookkeeper, father, and widower, is about to change his ways. It starts in a Fort Lauderdale parking lot, when Michael changes a flat tire on his pink rental car. Suddenly, the mild-mannered accountant, desperately trying to find a job and pay his daughter's mounting medical bills, is in possession of a load of pure, undiluted heroin. With a white-hot bag of powder and scarcely a clue, Michael leads the cops, the DEA, and one very sexy woman on a wild-goose chase through the deadly world of New York City drug dealing. It's a wild ride that might make Michael rich and might even land him in love - as long as it doesn't kill him.
