The forever war between Upper and Base is over. But that doesn't mean there is peace. Roslin has worked herself to the bone to join an exchange program that will see her as one of the first Uppers to visit Base in centuries. Her one burning desire: to escape the tyrant that is her father. Living among her former enemies seems safer than living with him. In her determination to keep out of her father's hands, she vows to do whatever it takes to stay. Even if that means alienating Sennai, the only friend she's ever had. Even if it means renouncing everything in her that is Upper. Even if she must endure the whims of Crayton, her host family's son. But when she discovers the darker side of Base society, she is forced to choose: turn a blind eye out of fear of her father; or find a way to help. After all, it's only world peace that hangs in the balance.
