Ava's an idiot who needs to get her priorities straight. Dax is an idiot who needs to stop being creepy. I hate them both.
If the story was more about them being stranded on an island, I'd enjoy it a lot more. Instead, Dax is snooping through her things, and every other sentence Ava thinks or says involves Preston. The story is written well enough, but it's stupid and so are the characters.
