Arianna is half-Fae, half something else. She's been a prisoner for the last six years, fighting as a gladiator in the rings under London. Now she's being forced to join the Shadow Fae, an organization that polices the creatures of the world, which has undergone significant changes in settings and politics. She needs to steal the World Key from Ruadan, one of the knights known as the Wraith. He doesn't speak but he's been appointed as her mentor.
It's an entertaining book with interesting characters, some based on historic figures. The Shadow Institute is based at the Tower of London, though it has been revamped for the Fae. The story definitely hooked me. Arianna has secrets, but she's also weirdly endearing. I definitely will continue the series. ( )

While not a terribly original read it was entertaining.

One thing that bugged me especially in the first half was the blatant man-hate.
At times it was so sexist that, if the genders were reversed, this would've been deemed unacceptable by many.
Especially early on it's one man-hate clichée after another and all the prejudices are of course conveniently confirmed every time.

This is the second time I tried this author and this one surprisingly overlapped with "Dark Fae FBI" which is the other one I've tried.
I got a very similar vibe as I got from Agent of Enchantment. Let's just hope the second book won't be as disappointing.

There are a lot of question marks I just can't properly judge yet. Edit: I've read the second book and I can judge them now. It's bad. Really bad. ( )
