It's like being there... only you can fast-forward and rewind. "I call it time-surfing," Abby said. "It's like being there, except no one can see or hear us." "Whatever you call it," John said, "that was crazy - what we just did. Beyond realistic. I mean, I was in that guy's head and knew everything he was thinking." Abby's weird computer program is working again. And it comes in handy when she and her friends agree to help the Old Dears with their family tree. Except Abby and John learn more about one of the ladies' ancestors than they ever wanted to know. Convicted in 1871 of murder and arson, Reuben Buchanan is a blight on the family's reputation. But was he really guilty? Abby and John must get inside the mind of a murderer to find out. And while they're rummaging around in the Old Dears' family history, they also find Nathan Buchanan, a heroic relative connected to the Lewis and Clark Expedition - and a legacy waiting to be reclaimed. But the most important discovery they make is that God's promise to bless a thousand generations is true.
