For almost a decade, zoologist Rachel Caine has lived a solitary existence far from her estranged family in England, monitoring wolves in a remote section of Idaho as part of a wildlife recovery program. But a surprising phone call takes her back to the peat and wet light of the Lake District where she grew up. The eccentric Earl of Annerdale has a controversial scheme to reintroduce the Grey Wolf to the English countryside, and he wants Rachel to spearhead the project. Though she’s skeptical, the earl’s lands are close to the village where she grew up, and where her aging mother now lives.
While the earl’s plan harks back to an ancient idyll of untamed British wilderness, Rachel must contend with modern-day realities—health and safety issues, public anger and fear, cynical political interests. But the return of the Grey unexpectedly sparks her own regeneration.
