I really enjoyed the first book and had to confine this series. This is set in Hawaii and is about Drew meeting her ex boyfriend's family for a Hawaiian vacation. Her ex doesn't show up and she is stuck with his grumpy brother, Josh. 

Their relationship is tense with each not knowing each other at all and both making assumptions about each other. As they spend more time together, the attraction grows. I love the tension in the story and forbidden trope.
