Three hundred metres down the slope from that same oak, a sealed chamber holds the record the keeping family built to protect what happened there, how the story continues in the present day, through a booby-trapped vault and a black-ops race to reach it first. In present-day Silicon Valley, a data scientist's gravimeter picks up a signal that shouldn't exist, rising from the roots of that same tree, and follows it back to the hillside. And in a Jerusalem compound, a priest living a double life has to decide what nine years of quiet devotion were actually for, once the modern world catches up to what his family has kept secret for millennia.
