2014 год. An ambitious Stone Age man demands a talisman that will harden his heart, allowing him to take control of his tribe. Against better judgement, the tribe’s magic man creates the Flint Heart, but the cruelty of it causes the destruction of the tribe. Thousands of years later, the talisman re-emerges to corrupt first a boy’s father, an innocent fairy creature and a familial badger. Can Charles and his sister Unity, who have consulted with fairies such as the mysterious Zagabog, wisest creature in the universe, find a way to rescue humans, fairies and animals alike from the dark influence of the Flint Heart? This humorous, hearty and utterly delightful reworking of a 1910 story by Eden Phillpotts, is perfect for an entire family to savour together or an adventurous youngster to devour.
