Scarlet by Marissa Meyer (2013) Feiwel & Friends

The granddaughter of a farmer/space pilot who went to the moon on a diplomatic mission is looking for her.  She’s been missing for three weeks, and the authorities are giving her the run-around.  What she doesn’t know is that her grandmother brought a horribly burned princess back with her and hid her for years as scientists strove to keep her alive.  Now the evil queen of the Lunars is looking for her to eliminate the last possible threat to her throne, sending an army of genetically modified humans with wolf traits and killer instincts to threaten Earth.  Will she find her grandmother?  Will she find the missing princess?
