An 11-year-old Martian girl named Lilac Pielikey is everything but ordinary. After watching the death of multiple siblings, and being rejected by her remaining family because she's a Christian, Lilac refuses to give up. After rescuing a cyborg girl named Rose, other Christian children start to follow them to the deserted planet Earth. There they form the resistance known as the Hidden.
After an earthquake destroys the planet, the Hidden are thrust into Lilac's other world. When they team up with Lily Pielikey, and Lily's daughter Ahyracie, things only get more complicated. The son of Lily's greatest enemy keeps them in the Fairy Lands, and when they finally get back to the Milky Way, earth is floating around in all directions, and in a million pieces.
Lilac made one of the most important decisions of her life when she said they should go back to Mars. The truth about her horrible past comes spilling out, and a deadlly secret. With a blade inches away from her heart, and a traitor at the end of it, there is only one way to escape. But will she make it?
