My Thoughts on Best Seller

Best Seller is a novel about a crime fiction novelist who becomes a character in her own story after agreeing to write a memoir. It’s a memoir for an elderly, rather eccentric older gentleman. She doesn’t think much of it. And then it’s a bestseller, and things start happening.

She doesn’t realize this, but within the pages of the memoir are clues sprinkled here and there that lead to a rare collection of jewels that were stolen during WWII.

This throws her into the fray. She’s caught between people wanting the jewels and the jewels, which she actually didn’t know about, and doesn’t know where they are!

Secrets come out. Danger abounds. Kelly has to choose between her bodyguard and her charming literary agent. Who will she choose? Who will keep her safe? And will the jewels be found?

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.
