Pete and Claudia hunt down an artefact at a prep school Hugo Miller's nephew attends, while Myka and Steve investigate an artefact in New Orleans. Artie has to deal with Brother Adrian's continuing investigations into Magellan's astrolabe.

A previously snagged artefact, Lewis Carroll's Mirror, turns up in a case and Alice is released into the world once more, but, this time, she is hunting something very specific, and will stop at nothing to carry out her goal.
