"It is the aftermath of a long war, in a world of constant winter. An intelligence spy from the Resistance - the rabbit, Hardin - steals secret information from a military base of the Regime. His actions set off a chain of events that reverberates through the ranks of both sides, touching everyone from Pavel the crow to Giles the goat, from the highest-ranking officials to the smallest orphaned child. When the snow finally settles, who will be the true patriot and who the true traitor?"--Publisher's web site.
