Batgirl #12

An unexpected call from the Bat-Family brings Cass up to speed on the happenings in Gotham and pushes Batgirl to dive headfirst into a mystery far beyond the streets she knows. What she uncovers is anything but expected. With new allies by her side, Batgirl must lead a dangerous mission to the snowcapped peaks of the Himalayas, where a war is brewing and long-buried secrets are waiting to be unearthed. The truth won't stay hidden forever... but some answers come at a cost — especially when Nyssa al Ghul is involved.
