In the fall of 1959, students drew pictures of life as they imagined it would be in 50 years for a time capsule. Lucinda, an odd child who hears voices, swiftly writes a long string of numbers. In 2009, the capsule was opened; student Caleb Koestler gets Lucinda’s “drawing,” and his father, John, an astrophysicist and grieving widower, takes a look. He discovers dates of disasters over the past 50 years with the number who died. Three dates remain, all coming soon. He investigates, learns of Lucinda, and looks for her family. He fears for his son, who’s started to hear voices and is visited by a silent stranger who shows him a vision of fire and destruction. What’s going on?
