An excellent read. Riley is an apprentice demon trapper and she's damn cool - a well rounded and likeable lead character. She's kick ass, sweet, funny and not in anyway bolshy. She's vulnerable too, which a key event early on in the book shows. I liked the story line and can see a number of areas where the series could go to. 
 I wasn't so keen on some of the linguistics - the Scottish master and Riley's father's 'partner' Beck's conversation was written in their accents (I know there's a techincal word for this - I learnt it in A-Level English Language but I've forgotten) which is something I really detest in books. The only person I think to have gotten away with it with me is Irvine Welsh because his books are a work of art. The use of 'ya' for you and 'ta' for to just annoy me - it suggests people are too stupid to remember that these characters have regional accents. However, it is easy enough to gloss over this. 
 I'm keeping my fingers crossed that there isn't going to be another love triangle/rectangle/octagon a la every single young adult paranormal book on the market these days because I really like the innocent relationship that Riley seems to have with Simon but I doubt I'm going to get my wish with all these mystery men showing up in her life. Unusually for me I'm not on the side of the bad boy in this - I'm not sure I really like Beck's character - sure, he really does care for Riley but there's something a little bit off about him for me that doesn't make him as likeable as I susoect he is meant to be. 
 I liked the details in the book - for example, the little Magpie demon who stole Riley's 'N' key from her laptop and then returned it - so sweet. 
 Looking forward to seeing where this goes.
