ENGLISH DESCRIPTION Javier Sierra (Teruel, 1971), "the king of Spanish conspirative thriller" (C. Geli, El Pa s) El fuego invisible is Sierra's eighth novel. Its protagonist is a young university professor and researcher from Dublin who spends a few days in Madrid. There he gets into dangerous investigations following the traces of the mythic Holy Grail. The novel, according to its author, "revolves around a word invented in the 12th century: Grail. And around the question of where the ideas come." "A fast-paced narration and a tremendous erudition about the topic (the author tends to have visited all the scenarios where his plots happen) mark a novel that fits well with the Sierra brand, well defined already in 1998 when he debuted with La dama de azul The lady in blue: a novel] in which, using the figure of the 17th century nun Mar a Jes s de greda, detained by the Inquisition, he plays with his famous bilocations to weave a plot with psychic CIA spies and experts from the Vatican. The success... was ratified with The Secret Supper, which he constructed from supposed criptic messages on the canvas of The Last Supper by Leonardo da Vinci and that brought Sierra to global fame, being published in 42 countries and selling more than three million copies. ... He has been called the Spanish Dan Brown, but better documented."
