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.

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.

So, pour yourself something warm, settle in, and step into the mystery of Best Seller — it’s only the beginning.

And remember, Love is a Mystery!

Interview with the Author

Which part of the book was the most difficult to write?

There are several angles of duplicity in this story, so keeping track of that thread throughout the novel was difficult. I ended up making a chart for myself. I was really happy how all the storylines came together in the final draft and I hope the reader enjoy it as much as I do!

What inspired this book?

WW2 history is fascinating and really tugs on the heartstrings. After I read several stories about book burnings, hidden art, and missing artifacts, I thought … what if? (I won’t give away what’s missing in Best Seller!) History should never be forgotten, and I hope my fictional books spur readers to search out history and preserve the stories of the past.

Which author influenced the you most?

Ted Dekker is one of my favorite authors of suspense. The worlds he creates, and depth of his characters influenced me to step into each new world I write and really try to understand the mind of my characters.

What is your favorite Bible verse or life verse?

I learned this verse at a very early age, and it always comes to the forefront of my mind when I step out in faith.

2 Timothy 1:7

For God has not given us a spirit of fear, but of power and of love and of a sound mind.

Describe your view as you’re sitting in your writing chair.

I love writing outside on my back porch (when it’s not too hot) where my view is a tiny woodland world of birds, deer and other critters who walk me through each season with their antics and happy sounds. Every spring mother deer walk their spotted little ones through the small trail to munch on bird seed dotting the ground. Hummingbirds, blue jays, and woodpeckers build nests when nature’s cycle begins again. My favorite? A family of squirrels tumble through the grass, wrestling like ornery toddlers, then dart toward the house to beg for a peanut. It’s my little writing escape in the middle of the city, giving me a space to breathe and be creative.
