Cryptids & Cauldrons: The Sisters - Cryptids & Cauldrons, #1

Dominik Esparza is a Research Agent for the ASPCA (A Society for the Prosecution of Cryptids and Assorteds). He spends his days categorizing demons, poltergeists, and the occasional rogue jackalope. Then he makes a mistake on a case that results in several civilian deaths. He's given a supervisor, Field Agent Danielle Belasco, and a new mission: to locate his best friend's sister, who was at the epicenter of his disastrous case and is now missing.
