Dallas is a time travel story about trying to kill President Kennedy. At one point the planet is destroyed. There are psychotic timetravelling hitmen and Number 5 is trying to stop a past version of himself.
I keep on digging the art in this book and Way’s approach to time travel (and the inaccuracy of such methods) was pretty sweet. This isn’t the kind of story you can just drop into, so make sure you read Apocalypse Suite to figure out who these characters are and why you should care first.
