Eternity Girl (2018 DC) #1A

Caroline Sharp has been a lot of things, including both a superhero and a super-spy. But now, with those days behind her and her powers proving unreliable, Caroline finds herself stuck in a life weighed down by her depression and an inability to change. You see, Caroline is going to live forever, and there is no escape to be had. The very act of living reminds her that, to the rest of existence, she is an anomaly. All of that could change, however, when her old foe, Madame Atom, comes to her with an intriguing offer. Madame Atom can give Caroline the power to end her life; she just has to destroy the rest of the world.
