The last wilderness - Erin Hunter

This title presents three bears' incredible journey. 'Hunter creates a richly sensuous world filled with cruelty, beauty, tenderness, savagery and just enough underlying legendary background to add mystery' - "Kirkus Reviews". After countless trials and an epic struggle for survival, the bears have reached the fabled last great wilderness...Prey is abundant, and people are scarce. Can the bears finally live in peace? Though the ice pulls Kallik, and the trees call to Lusa, it is Toklo who strikes out on his own, trying to exist in isolation as a fully-grown grizzly. But when Ujurak's life is threatened, the bears just come together once more to save their friend.
