I am not that far into the book. I just got to the part where, they are seniors, and she sees him for the first since the wedding. At the wedding, Nikki was upset from her break-up with Marco that when Luis tries to talk to her she doesn't say anything back. When Nikki's parents made her dance with Luis she kneed him and ran away. Her parents made her apologize, which she didn't, instead she hid his clothes on the beach so he had to be naked. So far their relationship isn't too good. So far I like it way more than I thought I would; the love story and all.
