"'My story is the story of all oaks; it didn't have to be, but it is.' With these words, the inquisitive, erudite, and chatty oak-narrator of Entwisle's Three Worlds Oak invites us to join it on a trip through history and around the world to discover the many branches of its family tree. We travel through China and Korea, North Africa, the British Isles, and the Americas. We learn about Druids' beliefs about the soul of the oak (it resided in parasitic mistletoe) and the number of trees it took to build a nineteenth-century ship in Britain (6,000). We learn about the life history of oaks as a genus and the individual life histories of scores of different oak species. Entwisle's book is a delight to read and as diverse in themes as oaks themselves are in ecology and form. I have bookmarked it densely and expect to come back to it again and again.".
