Books / academic writing on drone warfare?

I'm currently reading Gregoire Chamayou's A Theory of the Drone (2015), and although I've been appreciating it so far, I'm quite conscious of the fact that it has now been quite a long time since it was written. The use of drones in Ukraine, Haiti, and now of course Iran are all examples of later developments on which I keep thinking it would be interesting to read something like this, but unfortunately I am completely out of the loop when it comes to more recent writing on this topic. Would be very grateful for any recommendations, if people have them!
