Claude (Claudette) is a feline shifter and owns a pawn shop. She also happens to be a semi-retired "Collector." The Collectors pick up supes who are misbehaving. Jason is a gargoyle working for a magician. The Queen of Hearts is an elaborate ruby necklace that was stolen by Jason. Claude soon finds out not all is as appears.
This was good. I really adored Claude. She is strong, intelligent, and just plain awesome. Jason wasn't bad either. I liked that he was a gargoyle. I liked giving him a weakness that was then used against him. Very well done novella with the plotting and pacing.
