When vengeance calls from the mountains, even Batgirl can lose her footing. Batgirl Vol. 3 sends Cassandra Cain on a perilous mission—where the ghosts of her past and the sins of her mentors collide in a fight that could redefine her legacy. After a long, snowy trek through the Himalayas, Batgirl and her crew arrive at a hidden refuge deep within the mountains. But there’s no time to let their guard down as the Unburied threat returns seeking blood, and Nyssa al Ghul attempts to get Batgirl to join her cause against them. Dark secrets threaten to pull Batgirl into a war she never wanted and force her to confront ghosts from her past and present. Has Nyssa truly turned over a new leaf? And will Cass align herself with old enemies to exact justice against the Unburied for the murder of Lady Shiva? Find out as writer Tate Brombal ( House of Slaughter ) continues Batgirl’s All In journey alongside artists Takeshi Miyazawa ( Mech Cadet Yu ) and Stephen Segovia ( Secret Six )!
