This is just about the best news imaginable: Patti Smith's sequel to her heartbreakingly beautiful 2010 memoir Just Kids is coming this fall.

Entitled M Train, Smith's sequel memoir will cover the second half of her life, including her reflections on the loss of her husband, Fred "Sonic" Smith, of the legendary MC5. Just Kids, winner of the 2010 National Book Award for Non-Fiction, detailed the first half of her life, focusing on her relationship with Robert Mapplethorpe in particular.

Check out the cover above and this description of M Train below. It comes out Oct. 6 through Knopf.

And if you haven't read Just Kids, do it ASAP -- it's probably the best rock autobiography of all time.

"M Train is a journey through eighteen "stations." It begins in the tiny Greenwich Village café where Smith goes every morning for black coffee, ruminates on the world as it is and the world as it was, and writes in her notebook. We then travel, through prose that shifts fluidly between dreams and reality, past and present, across a landscape of creative aspirations and inspirations: from Frida Kahlo's Casa Azul in Mexico, to a meeting of an Arctic explorer's society in Berlin; from the ramshackle seaside bungalow in New York's Far Rockaway that Smith buys just before Hurricane Sandy hits, to the graves of Genet, Plath, Rimbaud, and Mishima. Woven throughout are reflections on the writer's craft and on artistic creation, alongside signature memories including her life in Michigan with her husband, guitarist Fred Sonic Smith, whose untimely death was an irremediable loss. For it is loss, as well as the consolation we might salvage from it, that lies at the heart of this exquisitely told memoir, one augmented by stunning black-and-white Polaroids taken by Smith herself."
