Query: Worth your time

This may story may disappoint the hard-core sci fi crowd whose first priority is imagined technology, and it will certainly scandalize some devout religious believers (if Christ can ask, "Lord why hast though forsaken me?" why can't the heroine?), but for the general reader it is a treasure. Among other insights, Willis' novel suggests that, despite all the earnest research, we may know only a little more about the past than we do about our future. But "Dooms Day Book" does testify to the endurance of the human race's saving virtues--compassion, fidelity, tenacity. If the human condition is to be improved, it will be more through their agency than through that of techonology. And like any honest and realistic narrative about the past, it leaves you grateful that you live now.
