Shut Up and Kiss Me

I was given an ARC by Netgalley.

I was a little confused about the genre of this book. Was is romance or New Adult?
Sometimes I forgot that the two main characters were in College - so it explained a little bit of their emotional maturity (or lack of it).
I didn't read the first book in the series and felt that it was ok to jump into the second. While I wasn't in love with this book (it was more of a meh....) I still want to go back and read the first book with Rena and Devlin.

I thought that the backstory could have been fleshed out a bit. There was a very small paragraph as to WHY Cade was street riding (to help his dad's gambling issue) but Cade never told his dad this was the reason or discussed it with him.
Maybe this is mentioned in book one - but why was Tash at the car crash in the beginning?
