The Unhoneymooners by Christina Lauren
Pack your bags: We’re going to Maui. Or at least our protagonists Olive Torres and Ethan Thomas are, thanks to a nasty case of post-wedding food poisoning that forces the bride and groom to offer up their honeymoon up to best man Ethan and maid of honor Olive. The only problem? They can’t stand each other, and they now have to spend the next 10 days pretending to be newlyweds. But soon Olive finds that pretending to be in love with Ethan isn’t nearly as hard as she thought it would be…
“Lauren brilliantly wields familiar rom-com tropes – enemies to lovers, fake marriage, even height differences – to craft a delightful romance that will have readers hanging on every word.” writes Publishers Weekly in a starred review.
