In 2003, my The Book of Eels was published to some praise from reviewers and general indifference on the part of the book-buying public. I wondered, at the time, why people could not be persuaded to share my fascination with such an amazing creature. But maybe it was just the timing, for not only was a new edition of my eel book published this summer, but now we have a Scandinavian perspective on eels from Patrik Svensson. The Gospel of the Eels caused a ferment of competitive chequebook waving at last year’s London Book Fair and has already appeared to acclaim in the United States. It’s no less than the creature deserves. The eel’s physiology, migrations and habits are extraordinary.
