This book was adorable and reminded me of Courtney Milan's contemporary romance novels (although Hoang and Milan have noticeably different authorial voices and it works).
Anyway, A+ representation, pretty good job with making the conflict either external or natural rather than forcing someone to act counter to character or in ignorance. (Also, well done solving the overstimulation issues by fixing the environment. It's the little things.)
This review is half in parentheses, so I'll stop now. The Kiss Quotient is an excellent example of what the contemporary romance novel can be and, despite the fact that I mostly refuse to read contemporary romance (I have a 19th century thing, it happens) and so my tastes are calibrated slightly off of what Hoang does here, I love that this exists and I enjoyed it.
