Daniel López Valle is the author of the book From him H.Ex. His stories trace the evolution of humanity, from the Ancient Age to the day Russia invades Ukraine in 2022.

His publisher suggested that he convert the spirit of his stories into workshops that would be taught at Casa Blackie in Barcelona. The last session on the 20th century will take place on April 15. On May 6, his next adventure will begin: courses on the history of Barcelona that will consist of four sessions until June 3.
