Follow flocks of arctic terns on their annual 40,000-kilometre journey between the Earth's poles. Join the monarch butterflies on their famous pilgrimage from Canada to Mexico. Awe at wildebeest, humpback whales, salmon, dragonflies and more. Find out how they navigate themselves on their impressive journeys - chemicals, the sun and or the Earth's magnetic field. Gloriously illustrated in Matt's signature watercolours, and described with his usual wit and charm, this is one book for any animal lover to treasure.
