The Old Guard series

Book 1: Opening Fire
Greg Rucka, Leandro Fernández (2017)

Old soldiers never die…and some of them don’t even fade away. Cursed with immortality, Andromache of Scythia and her comrades-in-arms ply their trade for those who can find—and afford—their services. But in the 21st century, being immortal is a difficult secret to keep, and when you live long enough, you learn that there are many fates far worse than death.

Book 2: Force Multiplied
Greg Rucka, Leandro Fernández (2017)

When you’ve waged war as long as Andy and her squad, you’ve gotten your hands more than bloody. Now, the day has come to confront the sins of the past. But as Nile struggles to make peace with the team, the last person Andy expected ever to see again returns to challenge not only what Andy believes in, but what the team is willing to fight for.
