In August 1592 a bailiff and his two assistants arrived at the monastery of Úbeda, with the secret task of moving the body of Fray Juan de la Cruz, the great Carmelite poet and mystic, who died the previous year, to his final dwelling in Segovia When when exhumed they find him "incorrupt and as fresh as when he died", an ecstatic fervor is produced by the body of the friar, who is only released for his pilgrimage, months later, in exchange for a leg or an arm, the sources disagree , stay in Úbeda. Along the way all kinds of adventures and misfortunes happen, with characters that seem to be drawn from mythological deeds, because not only is the body a coveted object of desire or fervent devotion - as if Brother Juan, who in life he was a great seducer, after his death he had become don Juan or the great seducer–, but the story told by Luis Felipe Fabre is masterfully intertwined with the verses of the friar, as if there were prophesies in them hoisted the delirium that would surround his own posthumous transfer.

Declaration of Dark Songs is a highly original work, where Fabre has managed to capture both the language and the tone and the mentality of the time in which the story takes place, at the same time that it gives it a very current character, retelling the myth by Brother Juan de la Cruz in a contemporary key. To do this, he uses a record that borders on the poetic delicacy of the Carmelite friar, who uses humor and the sense of the absurd to wrap the reader in a story that becomes timeless in his hands, infecting us with mystical desire - or not so mystical - that runs from beginning to end this prodigious novel.
