Spencer reminded me of Bo Novikov, a Shelly Laurenston character. He's so full of himself, but somehow it comes across charmingly. For the most part. 
 What worked for me: 
 -I liked the Twitter communications and how it featured in the romance, though it made me fell a little old and out of touch. I guess I am a little old and out of touch, though, so that's fine. 
 -I really liked Jazz and Spencer as characters 
 -It was funny! 
 -Very Hot!! 
 What could have been better 
 -the ending left me a little disappointed, but just a little. (view spoiler)[ I just wasn't totally convinced they wouldn't fall back into trouble again. Saying you're going to act differently and wanting to act differently don't mean you actually will. And this book definitely ended before we saw any changes. (hide spoiler)] 
 -there were times when Spencer crossed the line from charmingly conceited to gross and rude. This might not bother other readers. For me the good outweighed the bad, but there were definitely bad moments. 
 -there was an instance of Jazz saying "I didn't want it" after having sex with Spencer. I thought that was poorly handled. Jazz never accuses Spencer of raping her or forcing her, and it was clear in the scene that it was consensual. I guess it's just that I didn't like her vocabulary. 
 Overall the book really worked for me and I'll definitely read more by this author!
