Two weeks after that, the groundhog family emerged; the Sams, again looking out their window, were enthralled. Twenty years later, they’re still watching.

With Joe’s help, Susan has chronicled the lives of generations of groundhogs who made a home beside her own. She’s become an unlikely champion for creatures often regarded as vermin, killed for sport or because many people reach for a gun—or a trap or dry ice—rather than building a fence or filling in a hole. Their efforts have yielded a uniquely detailed, eye-level portrayal, perhaps even adding to what scientists know about the life history of a species at once widespread yet obscure.
