Anna pulls her three-year-old granddaughter a little closer, holds her a little tighter. She imagines sweet little Gracie growing up in a world torn apart by climate change, a world of catastrophic wildfires, floods, mass extinctions, resource shortages, and social upheavals. The thought is unbearable. She must do something, anything, everything to give the child a fighting chance.Anna reaches out to two childhood friends. Mac is a hard drinking, pill popping, pot-smoking professor of physics and climatology at the University of Wisconsin. Danny is an introverted landscaper who we meet at the Albuquerque ranch of his friend Jackson, a 79-year-old libertarian who is being investigated by the FBI and ATF. Mac and Danny dread the thought of waking the sleeping dragons of their collective history, but old loyalties and old fears propel them forward.In a desert house in Four Corners, New Mexico, the three friends come together for the first time in nineteen years. There, they reconnect, try to heal old wounds and reveal deep secrets that shaped their pasts and will transform their futures in ways none of them could have imagined.
