Letters from the Big Man: Sarah Smith, an artist and government hydrologist, sets out on a post-fire stream survey in a remote part of the Kalmiopsis Wilderness of southwestern Oregon. In the course of her journey through this ancient and ecologically diverse land, she unwittingly finds herself interacting with a sasquatch man, and a mutual curiosity ensues. As their friendship deepens, Sarah must take bold steps to protect his privacy, as well as her own.
