Marquardt, herself a child of divorce, conducted with Professor Norval Glenn, a pioneering national study of children of divorce, surveying 1,500 young adults from both divorced and intact families between 2001 and 2003. In Between Two Worlds, Marquardt weaves the findings of that study together with powerful, unsentimental stories of the childhoods of young people from divorced families. The hard truth, she says, is that while divorce is sometimes necessary, even amicable divorces sow lasting inner conflict in the lives of children. When a family breaks in two, children who stay in touch with both parents must travel between two worlds, trying alone to reconcile their parents often strikingly different beliefs, values, and ways of living. Marquardt makes a persuasive case against the culture of casual divorce.
