In theatres in Spain on September 12th, 2025. Coming soon to Amazon Prime Video. Full English version of the book coming to bookstores on September 23rd, 2025. Klara Rodríguez has barely left her house in eight agonizing months. Imprisoned by agoraphobia and anxiety, she has seen her world shrink to the walls of her bedroom, where every other night, one voice pierces through her isolation. It belongs to Kang, the soothing, thoughtful host of her favorite late-night college radio program. Then, an unexpected text message changes everything. Can you fall in love with someone you've never seen? Can a voice become your anchor in the storm? And is Klara strong enough to face not only the outside world but the person she loves?
