Tree houses are common, not least because Haretopia is populated by tree-huggers: in fact, hare-people hug all the time and mainly each other. Hare-people not only cherish trees and love getting lost in the woods but plant them to mark significant events in their lives. Instant acorns are a popular gift: ‘for an oak to grow - simply throw!’ Consequently, life histories of trees and people become so entwined that their stories can’t be separated in the telling.
