Rising above the city of Collis is the Holy Santcum. Catrin, an orphan girl, watches over its many spires with a unique skill that serves the Sanctum's master architect. But when Catrin witnesses a murder she is pulled into a dangerous chain of events where the only certainty is that the killer will strike again. The detective on the case is the brilliant and enigmatic Simon, whose insights into the mind of a predator are frighteningly accurate. As the grisly crimes continue, Catrin finds herself caught between killer and detective. But she's hiding her own secret - and it might be the only thing that saves her and those she loves from becoming the next victims . . .

Erin Beaty was born and raised in Indianapolis, Indiana and studied rocket science at the U.S. Naval Academy (really). After tours as weapons officer on a destroyer and a leadership instructor, she quit the navy to raise five kids, and once they were all in school, her brain didn't know what to do with that much free time so she started writing books. She and her husband make a home wherever the navy sends them, which has ranged from Kansas to Korea.
You can find her at erinbeaty.com and any coffee shop with a good cappuccino.
