Ms Terwiliger then drags her out to the middle of the desert so she can perform a spell, which she can't do herself because it has to be done by a virgin.
Sydney is invited to Sonya and Mikhail's wedding, as are the other two Alchemists that were on house arrest with her after the escapade with Rose.
Changing the subject, Sydney ends up telling him about Ms Terwiliger and the desert spell, and the fact that she is supposed to find one neighbourhood in L.A. At the wedding, Sydney is shocked by the strength of Ian's revulsion to the Moroi, who doesn't even want to shake hands with any Moroi.
Later in the evening, she goes outside in the moonlight with Adrian to do the spell again, this time to try to find Marcus Finch, and she sees a building in Santa Barbara.
Sydney's problems mount as Ms Terwiliger wants her and Adrian to go and warn potential victims of her sister (in disguise of course).
Sydney eventually decides to go to Mexico with Marcus to get her tattoo sealed, and finds it hard to say goodbye to everyone, especially Adrian, who leaves her a letter.
This is based on Jill's advice and a story from her and Adrian's old self-defense teacher, who told it to her when she went to return the gun she borrowed from him.
She follows the latitude and longitude directions Adrian left her, and finds him at a museum of Roman antiquities.
When she gets back to the school, she finds her little sister, Zoe, waiting for her in her room, with a golden lily on her cheek.
