 To Kill a Warlock is a light and humorous paranormal romance/urban fantasy about a fairy named Dulcie O'Neil and her adventures as a regulator (law enforcement) for Netherworld creatures and an aspiring romance writer. 
 When a known illegal potions seller is found dead, Dulcie is the prime suspect and must seek out the true culprit to clear her name. Soon after the murder a handsome stranger shows up claiming to be a Netherworld investigator sent to team up with her and find the murderer, but Dulcie finds more then she bargained for in this investigation. 
 With magic, romance, mystery, sexual tension and action, To Kill a Warlock was a fun and fast read. Mallory has created an interesting world with a vast array of paranormal creatures and a fresh twist in their abilities. 
 I loved the secondary characters in this take, especially Dulcie's three love interests; Knightly, Bram and Quillan. 
 Though I wasn't getting the feel of the main character and heroine, Dulcie. She is a smart, pretty and kick-ass fairy that is serious about her job but I found her personality and character development lacking. She had a bad relationship experience and because of her issues with that came off as a cold man-hater. She has three gorgeous men vying for her attention and she states in internal dialogues that she is attracted to each one, has feelings for one or two, but then she goes off thinking she would never be with any of them, turns them down and doesn't treat them very nice at all. The romance in this story was a big disappointment for me, I wasn't believing it, and is the main reason as to my rating of this novel. 
 There was a nice twist to the end though and I enjoyed the sub-plot of Dulcie writing a bodice-ripping pirate romance starring her boss. All in all a good read and I will continue with the series.
