Nara loves to make hats of all shapes and sizes for the animals who visit her workshop in the forest. Then one day she receives a letter from Mr. Mountain: he wants a hat, too. Nara is up for the challenge, and knits him an enormous woolly hat . . . which is perfect until it shrinks in the rain. The leaf hat is eaten, the stick hat burns to the ground. What other material can she try? The exploration of different materials and their properties makes A Hat for Mr Mountain the perfect picture book for primary STEM lessons.

This warm and humorous story about never giving up, and the importance of working together to help a friend is illustrated in quirky and exquisite detail. Look out for the mice making a smoothie! A masterful debut from the winner of second prize in the Macmillan Prize for Illustration 2018.
