Electric Shamans at the Festival of the Sun by Mónica Ojeda

Leaving behind the dread and decay of the city, Noa and her best friend, Nicole, travel up into the Andes, headed for Solar Noise: an eight-day festival that takes place on the side of a volcano. It is a world of shamanism and underground music, a world in tune with the thunder of the earth and the bellows of the mountains. Noa has been drawn there in search of her father, who abandoned her as a child, and who now lives somewhere near the festival site. But soon after their arrival, she begins speaking in a voice that is not her own. Believing Noa to be in danger, Nicole struggles to care for her friend. Until, as the party spills into Inti Raymi - the Incan festival of the sun - the girls' desire for belonging burns, incandescent, collapsing the thin membrane separating life from death, trauma from transcendence, and ecstasy from oblivion.
