Query: Engaging Biography

The story gets off to a bit of a slow start, but becomes very engaging as events in Onassis' life evolve. I realized this is because as a young person, Jaqueline Bouvier was just an ordinary little girl / young woman, who did not lead a very extraordinary life. But after her first marriage she becomes a participant and witness to so much that her story becomes very engaging. Bradford is a first rate biographer. This is not a trashy Hollywood accounting, but a thoroughly researched and compellingly told story of one woman's life.
