Dhampir Rose Hathaway, her former teacher, dhampir Dimitri and their allies must find out who killed the Queen, who was murdered in the previous book, and find her best friend Moroi Lissa's sister before Rose's trial. Following the death of the Moroi Queen and after Rose is being accused of killing her, Rose is in prison. However, soon enough Dimitri, Adrian, a Moroi prince who fell in love with her, and other friends are breaking her out. Dimitri drives her away to a hotel in order for her to wait while Lissa and her friends are helping clear her name. Rose tries to fight her friends and return to court, but Dimitri refuses to let her go back to help. She eventually manages to convince him to help her find Lissa's half sister.
Sydney, the Alchemist Rose met in Blood Promise, who also helps hiding Rose now, leads them to a group of Moroi, humans and dhampirs, where they are safe. They find out who knows the name of Lissa's half sister - a past teacher in the academy who turned herself into a Strigoi. With help from Victor Dashkov, who kidnapped Lissa and was broken out of prison by Rose in Spirit Bound, and Robert, his brother, they manage to turn her back into a Moroi and she tells them Jill, a new student in the academy, is Lissa's half sister. They set out to find her.
Once they find Jill, Victor and Robert kidnap her. Rose, Dimitri, Sydney and the teacher follow them and find them. Under the influence of Spirit, Rose gets angry and accidentally kills Victor. She is later comforted by Dimitri, who admits he still loves her. They sleep together and Rose decides to break up with Adrian. She also tells Dimitri that she cannot be with him unless he forgives himself.
Back in court, while trying to find out who killed the Queen, Lissa is in the running for Queen. She passes her trials successfully, but until Jill is brought into court, she is unable to actually be the queen. Rose, Dimitri, Jill and the others manage to arrive to court right in time. Rose presents Jill as Lissa's sister, and thanks to the alchemists, also presents the murderer.
The killer, Natasha, a Moroi related to Christian, Lissa's boyfriend, tries to kill Lissa and escape, but Rose takes the bullet. The guardians capture her. In her final moments of being awake, Rose believes she is dying - but she later wakes up in a room in court, Dimitri sitting by her side. He tells her she will be Lissa's guardian and he will be Christian's, meaning they can be together. Later, she finds out Lissa has been crowned queen.
