Shark Bait: Karma's Bite

Nina wants the island trip to end some other way than it did the first time. She went out there with her boyfriend and her best friend, a giant shark came at the group in the water, and the two of them, who had been sleeping together behind her back, pushed her in themselves. The shark took her. She opens her eyes at the hour she first stepped onto the island, with everything she saw still in her head. She uses it to pull a billionaire and a special forces soldier out of the path of the attack, then takes the island guide with her into a cave and waits there. The warning she gives the rest of the group gets her called crazy, and her boyfriend and her best friend keep the joke running for as long as they can. The shark comes in on the day she said it would.
