Kira Romanoff, retired teenage hero of the Avengers, is in a bit of a pickle. Firstly, she was captured by a bunch of alien thugs and carted all across the galaxy with a bunch of not-so-super superheroes. Secondly, when she returned to earth, she discovered that everyone that she'd ever known and loved, including her mother Natasha and her sisters Holly and Evie, were missing - vanished into thin air, and the only person who knows what happened to them is the annoyingly attractive apprentice of Doctor Strange. Thirdly, after a whole bunch of chaotic activities with the troublesome gods of Asgard, she was just spat out of an incredibly confusing space-time vortex into five years in the future, only to discover that half the earth's population had just been snuffed from existence. Warning: there will be chaos. And blood. Yes. A lot of that too.
