DNF. As much as I hate not finishing a book, especially when I've already invested my time into earlier books in the series, I cannot force myself to go on with this book or the series. 
 I have a deep and utter loathing of the main character, Katie. She is the dullest wet blanket to ever disgrace a page. She expects romance from an amazingly handsome, powerful wizard, yet does nothing to instigate it herself. She is so ordinary, boring, and unspecial that the romance is unbelievable. She catches on chapters and chapters later after the reader has already figured everything out. 
 Katie allows a conniving, ambitious coworker to take over her work area and her job. And MOST ANNOYINGLY OF ALL, the plot device that frustrated me in book 2 reappears in this book: Katie keeping a secret from Owen and Merlin that she should be telling them. If she fessed up to her inept and thoroughly unenjoyable to read about Fairy Godmother, maybe her relationship with Owen wouldn't be going so poorly. I'm sure just like in book 2, once the truth is revealed it will be easily solved by a flick of Owen's oh-so-handsome-and-sexy wrist. Did the author mention Owen was dashingly handsome and sexy several million times throughout this book just like the others? YES. 
 Also, Isabelle and What's Her Face don't have ANY lingering emotional upset after finding out what/who Ari is???? Poor continuity, there. 
 I don't know why authors have to have a tortured romance in their books. Why not allow the story to work it's own magic without frustrating your readers with a love life gone wrong? Is this a magic book, or a mystery? A romance, or a grown up take on Amelia Bedelia? I can't tell, and I don't care to ponder upon the matter any further. 
 I do not recommend this book to anyone. The writing isn't great, the characters are flat and unlovable after book one (except Rod, literally the only character I wanted to get to know better) and after reading the book blurbs on the later books in the series here on Goodreads, I feel absolutely confident about my decision to turn my back on this series once and for all without a backward glance.
