Enemies-to-lovers + a tropical holiday = the perfect setup for a blockbuster rom-com! Christina Lauren's The Unhoneymooners follows Olive and Ethan, the only members of a bridal party not to fall victim to a particularly horrible bout of food poisoning.

The only problem, of course, is that Olive and Ethan hate each other — at least at first.
