Chloe Horne Books in Order (Updated March 14, 2026)

Chloe Horne’s books are currently easiest to read in publication order, but not because they form one tight ongoing saga. The clearer pattern is a run of standalone billionaire romances built around familiar category-romance hooks like enemies to lovers, forced proximity, fake engagement, second chance, and off-limits attraction. Her official site and current retailer/reader listings surface the books as individual titles rather than as a clearly numbered series.

That means order matters less for spoilers and more for orientation. If you want the full Chloe Horne list, read by release. If you just want one book that matches your favorite trope, you can jump in almost anywhere.

The practical reading path

Because the books are being presented as individual romances, the safest guide is simple: start with the earlier 2025 releases and move forward. That preserves the author’s development and keeps you from starting with the newest title by accident.

Chloe Horne books in publication order

1. Engaged to My Billionaire Boss (2025): An off-limits enemies-to-lovers romance where a coffee-spilling first impression turns into a fake engagement with an arrogant billionaire boss, making it one of the clearest early examples of Horne’s trope mix.
2. The Billionaire’s Second Chance (2025): A grumpy enemies-to-lovers reunion story that brings an old relationship back into a high-stakes billionaire setting, and it works as the clearest early second-chance entry in the catalog.
3. The Bachelorette’s Billionaire (2025): An opposites-attract forced-proximity romance that turns a one-night mistake into a fake-engagement style setup, pushing the catalog further toward glossy, high-conflict billionaire romcom tension.
4. The Billionaire’s Mistaken Vow (2025): An age-gap forced-proximity romance built around a mistaken delivery to a penthouse, where a heroine from the art-gallery world collides with a powerful billionaire she was never meant to meet.
5. One Night With the Billionaire (2025): An enemies-to-lovers fake-relationship romance that fits the same fast, trope-forward style, best read here as part of Horne’s late-2025 run of billionaire standalones.
6. Snowed In With My Billionaire Boss (2025): An off-limits enemies-to-lovers romance that traps a temporary assistant with her grumpy CEO during a snow-in, leaning fully into forced proximity and seasonal pressure-cooker chemistry.
7. The Next Door Billionaire (2026): A friends-to-lovers second-chance romance where a childhood best friend becomes a fake boyfriend and bodyguard, shifting the setup from office tension to neighbor closeness and personal history.
8. The Billionaire’s Cupcake (2026): An off-limits forced-proximity romance that begins with a bakery fire and a rescue by the heroine’s brother’s best friend, giving the catalog a more playful bakery-and-fake-engagement angle.
9. The Billionaire CEO’s Second Chance (2026): An off-limits secret-child romance centered on a merger that reunites former lovers, and currently the newest clearly listed Chloe Horne title.

What kind of reading order works best?

For Chloe Horne, there are really two useful options.

Publication order is best if you want the full catalog and do not want to miss an early title.

Trope-first reading is fine if you are here for a specific setup, because the books are not currently presented as a tightly connected or numbered series on the author’s main public book list.

Best starting points by taste

Start with Engaged to My Billionaire Boss if you want the cleanest early entry point.

Start with The Billionaire’s Mistaken Vow if you want a strong forced-proximity setup with a sharper age-gap hook.

Start with The Next Door Billionaire if you prefer friends to lovers and second-chance energy over workplace conflict.

Start with The Billionaire CEO’s Second Chance if you want the newest book first and do not mind beginning with the latest standalone rather than the earliest one.

Is Chloe Horne writing a series?

At the moment, the safest answer is not a clearly labeled one in public-facing listings.

Her official site, Goodreads author page, and the retailer metadata I checked all emphasize the books as individual romances. Some stores explicitly mark titles like Engaged to My Billionaire Boss as “No Series,” which is why this guide treats the catalog as a set of standalones unless future author pages start grouping them differently.

Latest release status

As of March 14, 2026, the newest clearly listed Chloe Horne title is The Billionaire CEO’s Second Chance, published in March 2026. Before that came The Billionaire’s Cupcake in February 2026 and The Next Door Billionaire in January 2026.

Final recommendation

If you want one clean Chloe Horne reading order, read the books exactly as published:

1. Engaged to My Billionaire Boss
2. The Billionaire’s Second Chance
3. The Bachelorette’s Billionaire
4. The Billionaire’s Mistaken Vow
5. One Night With the Billionaire
6. Snowed In With My Billionaire Boss
7. The Next Door Billionaire
8. The Billionaire’s Cupcake
9. The Billionaire CEO’s Second Chance

That is the safest version of “Chloe Horne books in order” right now because it respects the current public metadata, avoids inventing a series structure that has not been clearly labeled, and still gives readers a straightforward path through the catalog.
