'I anticipated the release of Summer Fun for six years, and now that I finally got to read it, its characters and story will linger with me much longer than that. I suspect it will come to be considered the Pet Sounds of trans literature: a masterpiece that feels both astonishingly new and comfortingly familiar' ?Torrey Peters, author of Detransition, Baby Gala, a young trans woman, works at a hostel in Truth or Consequences, New Mexico. She is obsessed with the Get Happies, the quintessential 1960s Californian band, helmed by its resident genius, B----. Gala needs to know: Why did the band stop making music? Why did they never release their rumored album, Summer Fun? And so she writes letters to B---- that shed light not only on the Get Happies, but paint an extraordinary portrait of Gala. The parallel narratives of B---- and Gala form a dialogue about creation--of music, identity, self, culture, and counterculture.
