Amazon Reviews for Between Two Worlds

★★★★★

"A powerful, unflinching debut that bridges two worlds beautifully"

I picked up Between Two Worlds expecting a standard interracial romance, but what I got was so much more. K.J. Martin has written something rare — a novel that refuses to look away from the hard stuff while still delivering genuine emotional payoff.

Rose Namulondo is one of the most compelling heroines I've read in years. She's a Ugandan nurse who fled to Dublin after five years of psychological abuse, and watching her reclaim her power — not through a man's rescue but through her own meticulous documentation and quiet courage — was deeply satisfying. The author clearly understands trauma: the way it lingers, the way abusers colonize your inner voice, and the way healing isn't linear.

Tadhg O'Shea is a fantastic counterpart. He's a massive, stoic Garda sergeant with his own wounds, and the way he offers Rose his open hand (literally and figuratively) instead of pushing is beautiful. Their chemistry leaps off the page — and yes, the intimate scenes are both steamy and thematically rich, exploring race, desire, and reclamation without being exploitative.

The suspense plot is equally strong. The financial conspiracy stretches from Dublin to Kampala, and the author's criminal justice background shows in the procedural details. This isn't a romance with a thin thriller subplot — it's a genuine hybrid.

Five stars. Can't wait for Book Two.

"More than a romance — a story about surviving and fighting back"

I don't usually leave reviews, but this book stayed with me for days after I finished.

What struck me most was how Martin handles the racial dynamics. Rose is constantly navigating microaggressions at work, Ben's racist emails, and the complicated reality of falling in love with a white man in Dublin. The book doesn't pretend these issues don't exist or offer easy answers. When Ben calls her a "race traitor" and she has to wrestle with whether her attraction to Tadhg is genuine desire or something more complicated — that's real. That's honest.

The supporting characters are excellent too. Sylvia's parallel storyline about her abusive relationship with Chidi is heartbreaking and handled with care. Watching her find her voice at the gala was one of the most powerful scenes I've read this year. Eamon Cleary is a great addition — grieving, sharp, and clearly set up for more in future books.

The courtroom testimony scenes are gripping. Rose's cross-examination by Fitzpatrick had me holding my breath. This is a woman who's been documenting her own abuse for three years without knowing why, just because "that's what nurses do." That detail is brilliant.

My only complaint? The cliffhanger with the mole inside the Garda station means I'm desperately waiting for Book Two. Highly recommend.

"Atmospheric, suspenseful, and deeply romantic"

Between Two Worlds does something I didn't think was possible — it makes financial fraud and international money laundering genuinely thrilling. But at its heart, this is a story about two broken people learning to trust again, and it's heartbreaking and hopeful in equal measure.

The Dublin setting is rendered with such care. The rain becomes almost a character — persistent, grey, leeching warmth from bone. And when Rose finally returns to Kampala in the final chapters, the contrast in landscapes mirrors her internal journey. The prose is lovely without being overwrought.

I appreciated how slowly the romance builds. They meet on O'Connell Street during a traffic accident. He notices her handling a racist patient at the hospital. They have dinner. They talk — really talk — about their pasts. The intimacy feels earned.

The secondary romance between Sylvia and Eamon is a lovely subplot, and I'm excited to see where it goes. Two people meeting after surviving terrible relationships, choosing to go slowly, choosing honesty — it's refreshing.

Justice O'Brien, Superintendent Nolan, Aoife Quinn — even the minor characters feel fully realized. And the villain, Declan Byrne, is quietly terrifying precisely because he's so composed. No mustache-twirling here. Just cold, patient calculation.

My favorite line: "A nurse who kept charts. A woman who documented everything. The most dangerous kind of enemy."

Absolutely recommend for fans of Tana French's crime fiction, Kennedy Ryan's romance, or anyone who wants a love story with real stakes. Bring tissues for the mother's garden scene.

Between Two Worlds

A five-book interracial romantic suspense series set between the rain-slicked streets of Dublin and the red earth of Uganda. Love, conspiracy, corruption — and the stubborn, defiant hope that desire can reclaim what violence stole.

The Red Earth

Kampala & The Namulondo Estate

Eighty hectares of coffee trees. Red earth that stains your skin if you walk on it after rain. A legacy of murdered parents, a stolen inheritance, and a conspiracy that stretches from equatorial hills to Dublin boardrooms.

Scent: red earth, coffee blossom, jasmine

The Irish Rain

Dublin & The Wicklow Cottage

A city of grey stone where moisture simply is — a constant that leaches warmth from bone and colour from the world. A Wicklow cottage with walls that glow amber in firelight. A Garda sergeant who thought he was made of stone until the night he saw Rose in the rain.

Scent: roasted malt, turf smoke, rain on stone

KJ

Writing from the place where the law meets the heart

K.J. Martin is an Irish criminal justice professional who has spent decades inside the systems this series interrogates — policing, prisons, institutional corruption, and the quiet compromises that decent people make in broken structures.

Red Earth, Irish Rain was born from a question: What does it cost to love someone the world tells you not to? The answer required two continents, five books, and the collision of psychological depth with sophisticated WMBF sensibility — romance that reads like literary fiction, crime that cuts like truth.

The Uganda setting is grounded in real geography and cultural texture. The Dublin setting is the city as character — rain-soaked, malt-scented, fierce beneath its grey. The love stories are explicit, body-specific, and always in service of character. The heat is the brand.
