Sold into slavery, as children they work as daybreak girls in the house until they are old enough to become sundown girls, when they work for their keep in a very different way. They are called Good Luck Girls and are expected to believe they are the lucky ones because they live in relative comfort with plenty of food and most importantly, protection from the dangers of life outside the house. Revenants, vengeants and many others besides.
On Clementine's first night as a sundown girl, she accidentally kills her brag and has no choice than to go on the run. With her sister Aster and three other girls from the house, they plan an escape from the welcome house. But even then, with their tattooed favors marking them out, they face the constant threat of capture.
The story is told mostly in Aster's voice. Although she isn't actually that much older than Clem, she seems years older and is driven by her determination to keep her sister safe. She leads the group even though she isn't sure she has the strength, but when any of the girls are in trouble, she is unstoppable and will do anything to protect them.
The book is full of ups and downs. Moments of despair and times of relief, both touching and joyful. Reading a sample of the book, I thought it would be interesting but didn't expect to find it as engrossing as I did! I found it so hard to put down and hardly noticed the time passing. One thing I would have liked would be a bit more explanation. I don't think it is ever fully explained what is a dustblood, brag, or why they don't have shadows. Mostly I could guess but would have liked to know a bit more about some things. I wonder if there will be a follow up book. There is a satisfying ending but I feel like it has been left open to the possibility of more.
