Tat never expected a future. A lower-caste Luudi who left her planet and made a new home with a group of idealistic humans, she spends her time looking out for new family and working in secret to rescue refugees from a neighboring country. She is content with what she has, if sometimes lonely.

Then a Pros arrives their tense little border town. Although mostly human, the Pros were genetically engineered to look perfect and to offer pleasure, both physically and psychically. Beautiful, sophisticated Cin is no exception, which is why when she approaches Tat, Tat knows it can't be personal. Luudi are big, strong, purple, and impervious to psychic influence—making Tat the safest outlet for someone like Cin. Tat says yes with no expectation that Cin would ever want more, while convinced the danger will eventually drive Cin away.

But the Pros can take care of themselves, as well as any quietly heroic Luudi who catches their eye—if only that Luudi would let them. Tat has spent so long helping others find a future, it doesn't occur to her to seek out her own even when her silence might cost her the one she wants.
