Signal to Noise by Silvia Moreno-Garcia

Mexico City, 1988: Long before iTunes or MP3s, you said 'I love you' with a mixtape. Meche, awkward and fifteen, has two equally unhip friends - Sebastian and Daniela - and a whole lot of vinyl records to keep her company. When she discovers how to cast spells using music, the future looks brighter for the trio. The three friends will piece together their broken families, change their status as non-entities, and maybe even find love. In 2009, two decades after abandoning the metropolis, Meche returns for her estranged father's funeral. It's hard enough to cope with her family, but then she runs into Sebastian, reviving memories from her childhood she thought she buried a long time ago. What really happened back then? What precipitated the bitter falling out with her father? Is there any magic left?
