When money disappears first from the New Sage Shop and the from The Arc, circumstantial evidence points to Gwen as the culprit. Gwen must solve the mystery of what really happened to the money, while staving off the suspicions of an over-enthusiastic police detective.

When Gwen discovers that someone has worked a magical spell to prevent her from leaving the shop, she tries to figure out who is responsible through a series of flashbacks recalling her magical enemies: Reine, Morgana, Ms. Blatt. Meanwhile, Gadowain makes a nuisance of himself at The Arc when he decides to ingratiate himself to Michael's friends, hoping to persuade Michael to remove the iron bracelet and allow Gad to resume his job of protecting him.

When O'Leary arranges a car accident for Michael's parents and Mrs. Medina requires a blood transfusion, Michael is tested - and learns that through the blood results that there is an unusual component in his blood. Michael is sent reeling as Gwen reveals the truth: that, like Lancelot, he is half human - and half faerie. Michael decides to go to Faerie with Gadowain.
