{"product_id":"blue-john-book-berlie-doherty-9780140568721","title":"Blue John","description":"The Queen of Darkness lives under the ground in the shadow of a mountain, Mam Tor. Before she was carried down into the shelter of the cavern, she snatched the two things she could not bear to leave behind - the purple-blue heart of the glacier and the gold of the sun. Out of these she makes a child and names him Blue John. He lives in the caves with her, forbidden to go out into the light. One day a party of children comes to the caves and Blue John follows them out into the sunshine and is turned to stone. (Blue John is a precious stone mined in the Blue John and Treak caverns of Derbyshire. The name is said to come from the French bleu-jaune.)","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49546055450897,"sku":"GOR001779380","price":10.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0140568727.jpg?v=1750694348","url":"https:\/\/www.worldofbooks.com\/products\/blue-john-book-berlie-doherty-9780140568721","provider":"World of Books ","version":"1.0","type":"link"}
