Preternatural Too: Gyre

From the front flap of the Tor first edition: "Karen Guerreri is an obscure writer of pseudo-science fiction novels. Far from qualifying as a superpower in a world of mad-scientist villains, she is half convinced that her invisibility has left her alone and forgotten in the junk heap of literary black holes. She is still visited with visions of the intergalactic jellyfish known as the S. Oteri, and still listening to the bad advice of editors and agents, when a simple and startling idea pops into her head: She will write a sequel to her first book. Thus substantiating the reality of the first for a least a very brief time. Thus begins Preternatural Too: Gyre, surely one of the most improbable follow-ups in history. Skipping forwards and backwards in time, in and out of this world and teetering on the edge of sanity itself, Gyre stands like the proverbial shout into the void, like the tree falling in the woods with no one around, like the thundering clap of just one hand, and like a glass that is neither half empty nor half full."
