Fiery Heart (Bloodlines #4)
Sydney Sage is an Alchemist, one of a group of humans who dabble in magic and serve to bridge the worlds of humans and vampires. They protect vampire secrets - and human lives. In The Indigo Spell, Sydney was torn between the Alchemist way of life, and what her heart and gut were telling her to do. And in one breathtaking moment that Richelle Mead fans will never forget, she made a decision that shocked even her...But the struggle isn't over for Sydney. As she navigates the aftermath of her life-changing decision, she still finds herself pulled in too many directions at once. Her sister Zoe has arrived, and while Sydney longs to grow closer to her, there's still so much she must keep secret. Working with Marcus has changed the way she views the Alchemists, and Sydney must tread a careful path - or risk being sent to re-education. Her skill with magic is growing in ways she never imagined - but that doesn't stop the near-constant threat of evil magic users, Vampire Hunters, and Strigoi from growing ever closer.
Richelle Mead is the author of the bestselling Vampire Academy series, its spin-off series, Bloodlines, and the Age of X series.
