Immortals who have lived through the historical eras of the world is an intriguing concept ... and it feels like Rucka does about the least interesting thing possible with the concept: his immortals are mercenaries who run around and kill people and can't be killed. 
 The actual plot is a bit stronger than that premise, as it's about people finding out about the immortals, which could be a major turning point for their story. Maybe it still will be here. But here it just turns into a kill-fest with characters who are mostly undimensional. 
 With all that said, Rucka does write exciting action-adventure, but I'd be more excited if I thought there were any chance of the immortals losing. 
 I also find the artwork pretty ugly. 
 I'm likely to pick up another volume, but this book still hasn't grabbed me.
