1987. A visit from a long-lost relative brings the Langdons together again on the family farm; a place almost unrecognisable from the remote Iowan farmland Walter and Rosanna once owned. Whilst a few have stayed, most have spread wide across the US, but all are facing social, economic and political challenges unlike anything their ancestors encountered. Richie Langdon, finally out from under his twin brother's shadow, finds himself running for congress almost unintentionally, and completely underprepared for the world-changing decisions he will have to make. Charlie, the charmer, recently found, struggles to find his way. Jesse's son, Guthrie, set to take over the family farm, is deployed to Iraq, leaving it in the hands of his younger sister, Felicity, who must defend the land from more than just the extremes of climate change.
