Age Rating

The recommended age rating for The Unhoneymooners by Christina Lauren is 18+ based on some adult language and sexual content.


  • Ami Torres: the bride
  • Dane: the groom
  • Olive Torres: the bride’s identical twin sister and main-of-honor
  • Ethan Thomas: the groom’s best man
  • Sophie: Ethan’s ex-girlfriend

Summary (Without Spoilers)

Olive considers herself to be the unlucky twin compared to sister Ami, who is getting married to Dane. This time, she’s especially unlucky because the wedding festivities bring her into close contact with Dane’s best friend Ethan, who quickly becomes Olive’s nemesis, judging both her and her body.

But, when the entire wedding party EXCEPT Olive and Ethan gets food poisoning at the reception, Ami convinces them to come to a temporary truce and take their non-refundable honeymoon as a free honeymoon of sorts, since it’s bound to be the Hawaiian trip of a lifetime.  And since Olive and Ami are identical twin sisters, Olive can easily pass for her.  

In paradise, things get complicated quickly.  For starters, there’s only one bed in the honeymoon suite. Then, they run into both Olive’s future boss, as well as Ethan’s ex-girlfriend, who is there with her fiance. Olive and Ethan are abruptly forced to fake a marriage and pretend they are, in fact, on their honeymoon, in the face of these people.  And as they do, they begin to overcome their hatred and find some common ground… and romance.

Back home, however, it’s definitely not paradise, as Ami and Dane cope with early marital troubles.

The question becomes what will the post-wedding and post-honeymoon future hold for all four of them.


The Unhoneymooners has been one of my absolute favorite love stories since I first read it back when it was released and ALL the rage on Instagram.  

First, the “food poisoning at a wedding” is one of the funniest scenes I have read in any book to date, and I can still clearly picture it in my head. It reads like a movie scene.  From there, The Unhoneymooners offers SO much to the reader, from a hot Summer story at a tropical location to several swoon-worthy tropes, rom-com banter, and even some spice!

I know I’m just gushing here, but I truly consider it to be both a hilarious rom-com and the most perfect beach read. I highly recommend it!

The Honeymoon Crashers

Summary (Without Spoilers)

The Honeymoon Crashers picks up four years later, as the tables have turned.  This time, it’s Olive and Ethan who are getting married.  They seek a private ceremony in Maui, where they first fell in love, but Ami takes on maid of honor duties and flies the whole gang out to “surprise” them in paradise. There, she meets Ethan’s best friend and Hawaiin surfer, Brody, who’s determined to help her plan the festivities.  

Reeling from her divorce, Ami finds herself connecting with Brody.  The trick is to successfully execute all her best-laid wedding plans for her sister at the same time.  


As I mentioned earlier,  The Honeymoon Crashers is ONLY available on audio.  It offers a full-cast production that’s fun to listen to, especially since the narration switches.

Readers will especially love seeing Ami engage in some saucy flirtation with Brody.

It’s another delightful romance that’s short and sweet on top of it. There are all the pre-wedding mishaps you would expect from a rom-com like this one.

I think most readers will find it to be a fun update to a cherished book and beloved characters. It’s like the cherry on top of the… wedding cake?!
