In Ray Nayler's speculative novel of the recent past, four young teens caught between Nazis and the Red Army survive winter in the woods with the help of a flock of highly intelligent crows with a magnificent secret of their own to protect.
Neriya, a young Jewish girl who dreams of becoming a biologist, has befriended a local flock of crows in her shtetl. Czeslaw is an underage Polish soldier who deserts the Red Army and runs into the freezing Lithuanian woods. Kezia is a Roma horse trader whose family is on the run from Soviet collectivization. As the German blitzkrieg crashes across the border in June 1941, all three are caught up in the onslaught. Along with Innokentiy, an abandoned boy who cannot speak, they are driven into the primeval forest, where they survive by forming an unbreakable bond with one another--and with Neriya's intelligent crows, who for years have been bringing her intricate gifts suggesting they are no ordinary corvids. As the war goes on, the crows warn the children of danger and help them hide from the human threats of the forest--not only the Germans but also Russian deserters, Polish partisans, fascist Lithuanian police, and the other bandits and outcasts wandering the benighted landscape.
