Bloodlines, by Richelle Mead

The characters from the Vampire Academy series return for a new adventure, this time told from the point of view of Sydney Sage, the young Alchemist who reluctantly helped out Rose Hathaway in some of the earlier stories. The Alchemists despise all vampires and don’t distinguish between the ruling Moroi, the guardian Dhampir, or the evil Strigoi. But they are sworn to protect humans from vampires and so are drawn in to help prevent a damaging Moroi civil war that could have repercussions for everyone. The Alchemists view Sydney with suspicion because of her previous experience with the hated race, but it also makes her the ideal person to work with them again on this new task. The main players from Vampire Academy days take a back seat, with Lissa’s sister Jill, guardian Eddie and Rose’s ex Adrian taking centre stage. Sydney is between a rock and a hard place trying to navigate complicated relationships, do her job as an Alchemist and keep everybody safe and happy. She has to learn to stand up for herself to achieve this and solve a few mysteries along the way.
