Titan

What happens when an eighteen year old girl takes over a major corporation in 1920s Connecticut? Murder, infighting, and intrigue happen, set against the roaring twenties and the stock market crash of 1929. Kathleen Ryan goes on to establish herself as a major figure in American business, aided by her friends. Together, they teach men what women in business can do. Ruthless, violent, and crafty, the Irish girls take on the Depression, Roosevelt, and the Mafia.
Al Jolson plays a part as well, giving Kathleen's adopted daughter Veronica Manning her start in show business. Quite a long novel, but historically a good ride through the fifties, sixties, and up through the 911 disaster; Kathleen saw it all, and conquered it as well. Lots of action and classic cars.
