Before You by Jenna Bennett My rating: 4 of 5 stars Quinn, Mackenzie and Cassie are three college best friends and are on spring break vacation in Key West. Each book in the Sex on the Beach series focuses on one of these girls. Before You by Jenna Bennett focuses on Cassie and Tyler. Cassie is beyond ready to lose her virginity on this spring break vacation and when she meets Tyler and the sparks are flying, his refusal to come up to her room is a little surprising. She inherently trusts him but something is off with him. Let's add in the suspenseful storyline of... girls that look like her have been raped and can't remember a thing about who or why or how. Tyler could be the one doing it but cassie doesn't think so - so then who is the rapist and why do these girls look just like her? A romance with a twist that will keep you wondering till the end just who is good and who the bad guy is.
