What a satisfying book—it makes me want to grab a pack and head out the door. Sharman Apt Russell brings a tracker’s eye to the lives of wild animals, illuminating signs she finds with a curated wealth of natural history. With language as clear as fresh deer tracks in snow, she answers the important questions: why skunks are striped, how to tell a coyote's prints from a dog’s, and what drives a species toward or away from extinction. Readers who rarely look at the ground will have a hard time looking back up, and those familiar with tracking will be surprised by what they learn.
