Amadeu Fabregat, a journalist and narrator originally from Torreblanca, has had a distinguished career in media and literature. His previous works include Assaig d’aproximació a 'Falles folles fetes foc' (1974), awarded the Premi Andròmina de narrativa, the anthology Carn fresca (1974), and the socio-political essays Partits polítics al País Valencià (1976) and Converses extraparlamentàries (1978).

L'anell del nibelung marks Fabregat's return to narrative after nearly fifty years. This work is presented as a complex, harsh, and poetic story, far removed from easy entertainment. From the first glance, its density and depth capture the reader's attention, demanding a careful look at the lights and shadows of its discourse.

The book is characterized by the narrator's slow development of an autobiographical fable about returning to his hometown, driven by a personal obligation. The constant use of ellipsis as a narrative technique creates a cryptic tone, and the blend of memoir-like storytelling with transcendental reflections transports the reader through spaces with figures from the past that symbolize unresolved intimate conflicts.

Plot-wise, Professor Ernest Millet returns to the city of M. to witness the Wagnerian operatic tetralogy that gives the book its title. The stay, planned for ten days, includes his attendance at the operas Das Rheingold, Die Walküre, Siegfried, and Götterdämmerung, with the intention of self-reconciliation and the acceptance of murky past episodes. The work, published by Proa, has 568 pages and costs 23.90 euros.

The story evokes Ulysses's return to Ithaca and the figure of the Flying Dutchman. With an omniscient third-person narrative voice, the story is tense and intense, with extended paragraphs that demand an exercise in persistence and discipline from the reader. This work is considered a literary milestone that goes against the current trend of turning literature into an empty commodity.
