Ghost / Batgirl (Ghost / Batgirl #1)

When innocent people killed by Two-Face in Gotham City begin turning up as zombies in Arcadia, the original Batgirl, Barbara Gordon (now the computer wizard known as Oracle) and the new Batgirl, Cassandra Cain, take a road trip to Arcardia to find out what's really going on. But Ghost, the self-proclaimed Sentinel of Arcadia, is less than thrilled to have a new caped crime-fighter in town - especially since Ghost has her own reasons for wanting to discover the source of the recently resurrected. The Lady in White meets the Beauty in Black, and together they're going to paint the town red - blood red.
