The Darkness in Us: The Talish Trilogy Book 1

Her father died for his secrets. Now they might get her killed.
In the divided world of Talish, magic is power, and power is tightly controlled. As a Crafter, Natsu is told to keep her head down, her abilities hidden, and her future planned- a future that comes with working for the Mortal elite. But two years after her father's execution for practicing Dark Magic, all she wants are answers.
When a dead body turns up on her way to a blind date, Natsu is pulled into a chilling conspiracy that traces back to her father's forbidden research. Each clue drags her deeper into a web of lies, and each step forward comes with a body count.
As she delves into her family's past, Natsu discovers her father wasn't just wielding forbidden magic, he was creating a spell powerful enough to spark a revolution.
