In a future Chicago, sixteen-year-old Beatrice Prior must choose among five predetermined factions to define her identity for the rest of her life, a decision made more difficult when she discovers that she's an anomaly who doesn't fit into any one group, and that the society she lives in isn't perfect after all.

When Megan, Raf, and talking dog Bradley get their first real case, they find themselves tracking a puppy that is not as adorable as it seems, and trying to end an ancient curse.
