A team-up set up by SWORDS OF SORROW’s Gail Simone, featuring the writer that she hand-picked: Leah Moore! Irene Adler has been many things in her young life, a fugitive, a master of disguise and a femme fatale, but even she is surprised to find herself made bounty hunter, tracking savage foes across the grimy streets of London. In a far off world, defending Barsoom against an influx of trespassers, Princess Dejah Thoris is ready to put the guilty to her sword. Now, the world-colliding events of SWORDS OF SORROW have brought these dangerous women together… and the fate of planets hang in the balance!
