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.

Summer Fun is a brilliant and magical work of trans literature that marks Thornton as one of our most exciting and original novelists.
