Marine biologist, best-selling author and documentary-maker, Helen Scales searches for stories connecting people and nature. Her first book on seahorses, Poseidon’s Steed, was followed by the bestselling Spirals in Time, which explores the wonders of seashells and the animals that make them. A BBC Radio 4’s Book of the Week, it was picked as a book of the year by The Economist, Nature and The Times, and shortlisted for the Royal Society of Biology book award. She’s now following the trail of fish through the oceans for her upcoming book Eye of the Shoal.
