2.5/5
The premise of this is so good! It's such a shame it didn't reach its full potential.
First, you must ignore the huge, gaping plot hole. Like, you'd think with all the money Danny's father had, he would have been able to easily whip up some fake ids and documents for Danny, instead of coming up with his convoluted plan to lock and isolate Danny up in a tower. But that's fine! I was all into it. The story sounded deliciously dark; except, it wasn't actually very dark. Yes, the idea of whoring out Danny is dark, and should have been dark, but the writing didn't really present it as such.
Then there's the problem of having a whiplash of a story between the first and second half of the book. There was such a tonal shift, I believed it would have been better if the story was split into a duology. As it is, neither half of the story got the development it needed to really blossom into something great. Danny for instance was almost like 2 completely different persons, and it did not make sense in the short time skip we got. Perhaps if we had gotten more development and time to see Danny change, then it would have been easier to accept. It was also frustrating to see Danny declare he'd never be taken advantage again, and acting like he was such a 'badass" in control, when in reality he was still very much being taken advantage of by the Assassin guild. Ugh, I wanted to shake him by the shoulders so hard.
Lastly, the romance was supremely lacking too. The spicy scenes were good, but dear god, I hated Finn. I disliked him more than Danny's uncle. Danny's uncle was meant to be an irredeemable slime, but Finn was worse because he knew very well he took advantage of an innocent and left him out to dry. He deserved none of Danny's affections. Still, it was an easy read and I might check out more of this author's other books.
