I loved it.
Edited version. I got this for free and promised a review of it. I have already reviewed the book. And I had high praise for it. Listening to it the second time around got me a lot more insight into Riley and a lot of the careful insight Fiona has put into the setting and the characters. The narrator has a good capture for the sound of the character and a good vocal range, and is quite pleasing at a neutral tone. She's an easy read, but she did the entire narration in a boston accent and I didn't immediately get it.
The bostonian accent threw me for a loop but I had forgotten her close family ties to Massachusetts. Those family ties go back to the Summer Queen. Those ties are, I believe, deeper than immediately let on, and key to Riley's history. In short, what seems like a fun and quick urban fantasy read is actually an interlocking series of clockwork deeply involved and a serious contribution to the genre. Each of the characters feels like a well drawn person, and is worthy of exploration.
PJ Morgan is very talented. She has done a lot of other books including "How to Be a Man", "1Night Stand" and "The Muse" but judging by their blurbs it explains why she is so good a fit to read for Riley in these books. She will be an excellent fit for the other two books in the trilogy.
In short, if you have read the book, listen to the audio book. If you have listened to the audio book, read the book. Taming Shadows is definitely worth your time. I will now be listening to the second book in the series,"Silver Shackles."
