Seems like a lot of BDSM books popped up after the horrendous Fifty Shades of Grey came out, and this would be one of them. It doesn't deny it, constantly referencing those books. 
 The good? It's well written. The hero isn't an abusive asshole who disguises his abuse as kink. The heroine isn't a complete and utter doormat. 
 The bad, unfortunately, outweighs the good. The main offense is that it's boring. I skimmed so many of the sex scenes because it got repetitive. Politics got brought up a lot in the first half. Sometimes the book read like a How-To BDSM Handbook. Kate and Drake were both meh as characters. 
 The main conflict was Kate's so-called best friend being the main source of all the drama and I grew to despise her because she got so judgemental and bullheaded. In fact, I half-expected her to be a former sub of Drake's and was a bit disappointed that she wasn't. 
 That being said, if you like erotica, I'd definitely recommend this over those books.
