2013 год. This is a book full of creatures: birds, fish and mammals. They are all embarking on one long, intense journey that will take them across oceans and continents, for thousands of miles – braving predators, starvation and extreme weather conditions – to reach the very top of the world. Each spring, animals migrate north to spend their summer in the snow-melt Arctic. In this season, the sun rarely sets and so millions of animals – of over 200 species – are drawn by the rich food sources and safe breeding grounds. This adventure is the largest, most extraordinary migration in nature; it is beautifully captured in Nick Dowson's lyrical narrative and Patrick Benson's stunning illustrations.
