Not sure if this is new, but i wanted to mention it anyways:
DC#857 on sale September 2
"Elegy" part 4 of 4! Batwoman faces off against Alice in an attempt to stop the villainess from unleashing a toxic death cloud over all of Gotham! But Alice has more up her sleeve than just poison, and Batwoman's life will never ever be the same again.





DC#858 on sale October 28
The shocking and tragic origin story of Batwoman begins here! In "Go" part 1, young Kate Kane and her family are kidnapped by terrorists, and Kate's life – and the lives of her family – will never be the same! Plus, the mystery behind the villainous Alice is at last revealed!









Finally! the Origin of Batwoman, to me using terrorists seems like bit of cliche but Rucka is a great author so i am sure it will be a good story.

also for a little 'preview' of the back story on Batwoman, can be seen in that two page spread towards the end of this months issue.
