The only interesting thing about fourteen-year-old Jena is other people. Her mother disappeared when she was a baby, and her best (and only) friend, Sisi, is not just the lost heir to a noble Numbered house, but also the Kingdom’s most famous beauty. Jena herself is just awkward, anxious, and often alone: not exactly heroic material. But when a letter summons Sisi to the royal court, both girls find their own futures, and the Kingdom’s, in Jena’s hands. Sisi, caught between the king and the crown prince, searches for a magical secret the Prince is willing to kill to keep. Jena can save her: but only if she is willing to let her go, maybe forever. It’s hard to do that when she’s in love with Sisi herself.
