"On a devastated future Earth, military cadet Jax and migrant Naomi join an epic quest to stop a terrifying alien invasion!" as opposed to those invasions that aren't remotely terrifying and in fact are quite fun? Barf. And once again, we have the most over-employed go-to guy Jack - or in this futuristic version, Jax, which is just as bad. Do these authors have no imagination? So, no thanks. I'll catch the next "terrifying invasion." And what's with that ninth city? I'll bet it's the ninth US city, not the ninth in the world, because who cares if the rest of the world is burning?!
