A poetic and playful tale about the joys of going outside and having adventures - beautifully illustrated by Emma Chichester Clark, creator of Plumdog.In a mansion surrounded by lakes and forests, Frederick is very bored. He leads the most sheltered life imaginable: and when Emily invites him to play outside he has no choice but to refuse - what if he hurts himself? Much better to stay safely indoors. But Emily is not one to take no for an answer.A series of brilliantly funny and evocative letters between Frederick and Emily form the frame of this unique story which weaves together the colourful, adventurous world of Emily with Frederick's drab life of boredom and safety.
