Even if you've already read Christina Lauren's 2019 book The Unhoneymooners, it's worth it to read it again! This enemies-to-lovers romance is full of zingy one-liners in a beautiful Hawaiian landscape. Olive is the unlucky twin, always living life in her sister Ami's shadow. So after Ami's entire wedding party gets food poisoning except Olive and her nemesis Ethan Thomas, she gets the chance to go on the trip of a lifetime — as long as she can put up with the annoying best man in the process. A romantic island honeymoon with two enemies pretending to be newlyweds . . . what could go wrong?
