But meanwhile, Cassie's brother, Sam, has been taken. 4th wave was when the remaining humans realized the aliens were already on earth, masquerading as humans. 3rd wave was when an airborne virus swept over the world, killing millions. 2nd wave, an earthquake large enough to wipe out cities and cause devastating tsunamis. Six months ago, aliens made their presence known, and have been killing humans in a series of waves. This sci-fi book introduces us to Cassie, and her recently destroyed world.
Though no matter where you run, you won't be able to escape them. This is one alien invasion you do not want to be in. Sign me up for the first to avoid an alien invasion.
And if this is humanity, then I am the battlefield.'
