Barcelona-based writer Alba Muñoz makes her debut with Polilla (Alfaguara) "I expected to fall to my knees, double over in pain, and it didn't happen," she says. The eureka moment, the one in which everything falls into place and suddenly makes sense, came in the most unexpected place.

The horror awaited her, unexpectedly, painted on the walls of the old battery factory that guards the tombs, an abandoned building that one day housed the headquarters of blue helmets in charge of ensuring the safety of refugees.
