23 Enemies-to-Lovers Books That Turn Rivalry to Romance

"The Unhoneymooners" ($9)

In Christina Lauren's "The Unhoneymooners," a wedding-gone-wrong sends the maid of honor and the best man — who happen to hate each other — on a would-be honeymoon in paradise. When food poisoning takes out the entire bridal party except for Olive and Ethan, they reluctantly agree to do a big favor for the bride and groom: take their spots on the trip that was supposed to be a honeymoon so the money isn't wasted. As much as they loathe each other, Olive and Ethan slowly start to settle into their fake roles as happy newlyweds, but a new revelation of betrayal soon threatens their tentative truce.
