In 2038, scientist Jake Greenwood is working as an overqualified tour guide to ultra-rich eco-tourists in one of the world's last remaining forests. As the rest of humanity chokes on the dust storms that follow the environmental collapse known as the Great Withering, Jake finds temporary refuge on Greenwood Island, a place whose connection to her own family name she had thought just a coincidence -- until someone from her past reappears with a journal that might give Jake the family story she's long craved. As we move backward in time from the Great Withering to the Dust Bowl of the 1930s, and then forward into the future again, we meet an injured carpenter facing the possibility of his own death, an eco-warrior trying to atone for the sins of her father's rapacious timber empire, a blind tycoon with a secret he will pay a terrible price to protect, and a Depression-era drifter who saves an abandoned infant from certain death, only to find himself the subject of a country-wide manhunt. At the very centre of the book is a tragedy that will bind the fates of two boys together, setting in motion events whose reverberations will be felt for over a century. A magnificent novel of inheritance, sacrifice, nature, and love that takes its structure from the nested growth rings of a tree, Greenwood spans generations to tell the story of a family living and dying in the shadows cast by its own secrets.
