A fugue state is a form of PTSD, and Nathan has it. He loses time, can’t remember important things, and gets angry about certain topics for no real reason he can remember. Naunie is his childhood friend who’s come back into his life. She’s concerned about him, but dealing with some of her own trauma.
Fugue is a short story, more of a novella than a novel. Personally, I had trouble with this book because I felt like there was more history of the characters than there was real story. This is a duel protagonist story, with both Nathan and Naunie’s problems featuring in the forefront.
