This was one I picked up on sale and for the tattoo theme. It had some potential but the way it was executed was not good. Ethan's situation was really not conveyed in a way to create any empathy with his character. There were vague references to being "hurt" by Charles but nothing was mentioned other than bruises. He was evidently cutting, but there was no development or follow up about what drives someone to that, and he simply stopped when Niko told him to. No, that's not how a psychological condition like that works. Also, his parents still paid his tuition, so I'm not sure why getting a job, living in a dorm and paying his own way to begin with, wasn't an option. No genuine supporting reasons for his arrangement with Charles. No character building was done to make his character truly relatable.
Niko had little buildup either. Most of his story came out near the end of the book, and it was still not much to support his denial of being gay and determination to sleep with women. The scene where he helps his openly gay work friend was ridiculous and rather disgusting. I don't, and many MM readers don't want to see any MF sex in their books, either. His come-ons and pursuit of Ethan was weird. All the sex scenes with Ethan were weird. Wake up a guy you've known for like one day, who says he's not gay, with a rim job? Sure, why not, right?
Then there was the whole threat and blackmailing Ethan thing. There wasn't much about who the hell Charles was and Mitch, the supposed lawyer, did something or other to make it go away. Whatever he did was unclear, undefined and I could make little sense of what it was supposed to mean. But somehow Ethan and Niko got an HEA out of it. Needed a lot of editing for errors as well.
