The original "Black Hole Rising" story planned for October 11's The Flash #32 has been pushed back to November 8's The Flash #34, with a new story taking its place.
The Flash #32 will now feature the story "Welcome to Iron Heights" by series writer Joshua Williamson and guest artist Christian Duce (who previously drew The Flash #29). Kelley Jones will illustrate a new cover as well.
"In this story, it's Barry Allen's first day on the job at Iron Heights Penitentiary, and it does not go very well as Warden Wolfe proves to be an even more demanding boss than Director Singh at the CCPD Crime Lab!" reads DC's new description for The Flash #32. "And to top it all off, a ghost from Flash's past comes back to haunt him!"
No reason has been given for the change, or what will come of The Flash #34's originally-planned story.
