Follow the ebbs and flows of Sarah Henshaw's journey as she sought to make her vision of a floating bookshop, The Book Barge, a reality. Business wasn't always easy, so one May morning she set off for six months chugging the length and breadth of the country. Books were bartered for food, accommodation, bathroom facilities and cake. During the journey, the barge suffered a flooded engine, went out to sea, got banned from Bristol and, on several occasions, floated away altogether.
