It’s been nearly two decades since the Red Allies first attacked New York, and Manhattan is now a prisoner-of-war camp. For Skyler Miller, Manhattan is a cage that keeps her from the world beyond the city’s borders. But for Sky’s younger sister, Phee, the POW camp is a dangerous playground of possibility, and the only home she’d ever want. When Sky and Phee discover their mom’s hidden journal from the war’s outbreak, they both realize there’s more to Manhattan --- and their mother --- than either of them had ever imagined.
