The Indigo Spell

The Indigo Spell is a 2013 fantasy novel written by the American author Richelle Mead. Released in February 2013, it is the third novel in Mead's book series Bloodlines.

The book starts with Sydney being woken by her history/magic teacher and asked a personal question. 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 still resistant to learning magic, but does the spell anyway. Her teacher is worried by Sydney's findings, as it means her older sister is nearby, and she uses an evil spell to suck the youth and power out of teen girls, which means Sydney may be in danger. Ms. Terwiliger tells Sydney that she has to develop her magical skills quickly, whether she wants to or not.

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. This is because the Moroi are trying to make amends to them. She is supposed to be flying separately from Adrian so people don't find out they are in the same place but, due to an overbooked plane, Sydney gets switched to Adrian's flight. She tells him he can't love her, but he says he is going to keep doing so whether she loves him back or not, and he is convinced she is in love with him and just doesn't know it yet. 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 neighborhood 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. Sydney is the put on the spot when Adrian asks her to dance in a show of fostering good relations. She accepts, and Sonya and Rose comment on how good they look together, troubling Sydney. 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.

Back in Palm Springs, Sydney has to fix Angeline's math problem by finding her a tutor, and eventually Trey agrees to do it, but little does she know, that leads to Angeline cheating on Eddie with Trey. Sydney's problems mount as Ms. Terwiliger wants her and Adrian to go and warn potential victims of her sister (in disguise of course). That leads to romantic interludes, including one that leaves her with a hickey. Sydney keeps telling herself to forget about them, and is in complete denial of her feelings for Adrian.

She finally finds Marcus, but not before ending up in a fight with him. She sees a girl who was with the Warriors with Marcus, and learns that she is a double agent. She discovers that Marcus finds Alchemists and Warriors that want to leave their groups, and helps them. He also says that he can break the group compulsion in the Alchemist tattoos, but that she has to pull off a mission to collect evidence of Alchemists and Warriors working together first. She uses Ian's crush on her to get access to an Alchemist facility and, using magic, collects the information she needs. She then agrees to the breaking her tattoo process, but almost gets herself into a trap by questioning her superior. She has to cover her tracks, but her quick thinking has unforeseen consequences.
