En plena noche (Trilogía de Illumbe 2) by Mikel Santiago

Set in the fictional Basque village of Illumbe, En Plena Noche charts the return of Diego Letamendia – once rock-star, now a man haunted by the night his band ended and his girlfriend disappeared. With the memory of that concerted final gig still burning, Diego left Illumbe and sought solo stardom. Two decades later, a bandmate’s mysterious death in a fire pulls him back into a place filled with lies, silence and unanswered questions. 

As old friends converge, none of them are who they were. The investigation leads Diego into hidden corners of the village and a night that refuses to end. With nostalgia for the 1990s and the weight of unresolved grief, the narrative blends music, mystery, and the small-town tension of the Basque Country. 
This second instalment of the Illumbe Trilogy amplifies the stakes: secrets that were meant to be forgotten now spark reckoning. For readers of psychological thrillers and atmospheric, slow-burn mysteries, this novel offers layered characters, a haunting setting, and a dark past whose echoes reach far into the present.
