The alien invasion of Earth is imminent. But maybe not all the aliens are united. A rebel faction has reached out to Anaya, saying there's a way to stop the larger invastion--a way for humans and hybrids and cryptogens to work together. Can they be trusted? Or is this a trap? It's not even clear if Anaya, Petra, and Seth are united--some of the hybrids think they'd be better off if the aliens won... With everything on the line, these three teens will have to decide who they are at their core--alien or human, enemy or friend.
