Olivine, the fourth of seven sisters, has been hiding a secret as she travels to K'ba to meet her artist friends. Others assume she has fallen in love with another artist, and it's not a match Mother would consider suitable. But it's much worse that. For on the way to K'ba is the dirt poor nichna of Scrud, a place scorned by all other Ilarians. And in Scrud is the one man who understands her.

However, Bohdan is also is a realist, and a man who recognizes the dangers posed by an impending Mongol invasion. When he learns of Olivine's unusual visual powers, he convinces her to pick up her bow and arrow and start practicing.

She does, though she's more concerned with producing enough art to raise the funds to run away from home and live in K'ba, where she can paint all day and see Bohdan as often as she wants. If only her sister Ryalgar hadn't learned of what she can do and decided Olivine and her fellow long-eyes held one of the keys to defending the realm.

Then, as if life wasn't complicated enough, Olivine learns the artist community she yearns to be part of has developed a different take on the invasion. They feel certain the only way to survive is to capitulate completely to the Mongols demands. Artists who feel otherwise are no longer welcome.

Where does her future lie? The supposed invasion is coming soon and Olivine doesn't have much time to decide.
