On the Surface is a mystery about Dani Fox and Sawyer Stone, an unlikely couple that have chosen the cruiser life in the Bahamas. Dani is trying to get their YouTube channel to monetization levels and Sawyer is working hard to keep their beat up boat seaworthy. The couple is somewhat ostracized from their local cruiser community; they aren't boomers, they don't bring booze to share at parties, and really it seems like Dani's physical appearance is why people put up with them. 

So when Dani disappears after a raging party, everyone suspects Sawyer. He swears to his innocence, but he has secrets too. This plot slowly unravels alternating between perspectives from the couple and an investigator in the Royal Bahamas Police Force. I really enjoyed the relatively short chapters and the slow and steady unraveling of Dani and Sawyer's pasts. 

I think you'll enjoy this one if you like beach settings, a steady drip of reveals, and stories that examine social media influencer culture. This would make a great spring break or summer vacation read.
