Book excerpt: In the middle of a perilous drought in the Northwest, an arsonist begins setting fires all around. It gives Zoe Penney nightmares about her home—seated right next to tinder-dry woods—rising up in explosions of fire, as well as haunting dreams of a little boy deep in the forest. Winter brings the longed-for rains but also a cancer diagnosis for Zoe’s husband, Jay, which plunges the family into disbelief and fear. The children lean in close to their parents, can’t stop touching them. As Jay’s treatment begins, nature lets loose with strange and startling encounters, while a shadowy figure hovers about the corners of the house. First, Zoe’s fear turns to anger: How can I love you if I am to lose you? How can I live in joy when the sky is falling? But she gradually learns that it’s possible to love anything, even terrible things—if you can love them for what they are teaching you.
