"Three years ago, aliens invaded Earth and abducted everyone they deemed useful. The only ones spared were those too young, too old, or too "disabled" to be of value. Living on Earth under the aliens' harsh authoritarian rule, humanity's rejects do their best to survive. Their captors never considered them a threat--until now. Twins Sam and Wyatt are ready to chuck their labels and start a revolution. It's time for the kids last picked to step into the game."--Amazon.com.
