Now, instead of enjoying her rise to literary fame, she’s thrust into the dangerous world of treasure hunting.

While Kelly struggles to win the game of cat-and-mouse, a secret family legacy is unearthed, forcing her to choose between trusting her charming literary agent or her vigilant bodyguard to keep her safe.

As the three of them become entangled in a web of deceit, it’s a race to see who’s the villain, who’s the hero, and who holds all the pieces to solve the mystery of the best seller.

Author Interview

1. Do you consider yourself a plotter or a pantser (or a hybrid)?
Pantser! I usually write a lot before I start really trying to make a timeline.

2. What is your favorite part about writing?
Meeting the characters and learning what quirks and layers to their personality they’ll
have. It’s fun to learn their favorite drinks, favorite foods, sleep habits, or choice
vacation destinations, even if I don’t use all of that info in the story.

3. What is your least favorite part about writing?
Editing. I’m a terrible editor. I love to mood read, so I get lost in the story and miss
mistakes.

4. Do you have a way to keep track of your story ideas?
When a story idea strikes, I use my notes on my phone, or I open a Word doc and free
write for a few minutes. After that I make a new folder—usually I have a title in mind that
I save it as and add it in my “book ideas” folder. Currently I have over twenty folders
saved, some with a paragraph written or a whole page and a few have over 10K words.

5. What is your writing space like?
We have an office at home, and my husband built us matching desks on opposite walls.
Well, they were matching until this winter when he built bookcases on mine up to the
ceiling! A girl needs a place for her books, right? I have a space for my Bible study
notebooks and journals and a space for work (I work online as a VA). I have my laptop
and two additional monitors, (hubby’s idea) so I can easily go between docs when I’m
editing or researching. I love Nutcrackers, so I have one year-round on my desk, and an
essential oil diffuser. My kitty has her perch right to me so she can lounge around and
keep on an eye on what I’m doing while watching squirrels out the window.

6. How long does it usually take you to write a book?
Usually about a year, if I’m under contract. Otherwise, I just write and let the story unfold
on its own time.

7. Where do you get your ideas for your books?
Everywhere. It could be a location, smell, or a song. I’m always collecting “things” for
stories—old post cards, one-liners, quotes, poetry, or playlists. I was at a baseball game
last year and an idea hit—Baseball, love-at-first-sight, political intrigue, food truck and
maybe an art heist. I’m not sure how all that would go together, but that’s how the spark
hits!

More from Christina

There is a certain in-between place where creatives tend to linger — a space where reality meets imagination and stories quietly begin. It’s where we observe the world as it is, then wonder how it might unfold just a little differently. That space is where my writing lives, and it’s where Best Seller was born.

Before novels, though, there was coffee. My very first “real” job as a teen was working as a barista, and I loved it. I wasn’t just making drinks — I was mixing flavors and letting my imagination wander between orders. There’s something comforting about coffee, something that invites reflection and creativity. Looking back, it makes perfect sense that it found its way into my stories.

In Best Seller, my main character Kelly Landon is a crime fiction writer with a carefully guarded heart. She’s shy, introverted, and far more comfortable with quiet moments than crowded rooms. Her love of seasonal coffee blends mirrors her inner world — thoughtful, layered, and hopeful beneath the surface. But Kelly’s heart is fragile, and without being anchored in God’s love and truth, it can be easily swayed by the promise of earthly acceptance.

Enter Declan — her outgoing literary agent with unassuming Irish charm and a way with words. Can you blame Kelly for daydreaming? For wondering if love might be possible after all?

To celebrate Best Seller, I created the Writer Girl Latte, inspired by my barista days and Kelly’s story. Cozy, creative, sweet, and just a little indulgent — because sometimes the best stories begin with a warm cup and a willing heart.
