As former Alchemist Marcus Finch pushes Alchemist Sydney Sage to rebel against the people who raised her, Sydney finds that breaking free is harder than she thought. There is an old and mysterious magic rooted deeply within her. And as she searches for an evil magic user targeting powerful young witches, she realizes that her only hope is to embrace her magical blood–or else she might be next.
I love companion series, they make the original series so much fuller and you get to see more of that world! Sydney begins to realize that she no longer embraces the Alchemist rules like she used to, the more she is with the Moroi and dhamphirs she is assigned to. Finding out you have been lied to can also be unappealing to someone with the brains to figure it all out. A good continuation of the Alchemist side of the story.
