Éditions Mercia du Lac was created in Lausanne, Switzerland in 2017 by the Didier family, who have been in publishing for several generations. 

The main author, Danièle Didier, has dedicated herself to writing books specialising in personal development such as energy sciences and arts, divinatory arts, feng shui and spirituality. 

These books bring a wealth of teaching through their new, complementary and fundamental insight into age-old knowledge.
