If Stephanie Plum had a Texas-born, Marine-trained cousin... her name would be Rowan Grace Walsh.

DETECTIVES THAT CROSS OCEANS - BOOK FIVE: Friend or Foe

Clean Christian Suspense . Ireland Setting . Betrayal, Loyalty & High-Stakes Investigation

Danger doesn't always come from the shadows. Sometimes it walks beside you, wears a badge, and speaks in a familiar voice. After surviving a sniper's bullet and a bombing that shook Dublin to its core, Rowan Grace of Texas and Aidan Murphy of Ireland step into their most personal investigation yet - one where the enemy may be closer than either of them wants to believe.

As Rowan fights to recover from her injuries, Aidan uncovers evidence linking their recent attacks to a series of unsolved cases stretching back years. Every clue points to a threat operating from within - someone who knows their movements, their weaknesses, and their partnership. Trust becomes fragile. Loyalty becomes uncertain. And every decision carries a cost.

Together, Rowan and Aidan navigate a maze of betrayal, hidden motives, and long-buried secrets. Their bond - once forged in fire - is tested in ways neither expected. With danger closing in and allies turning questionable, they must decide who stands with them, who stands against them, and who has been watching all along.

In this chapter of their journey, courage is found not only in the chase but in the quiet moments when fear whispers louder than truth. Faith becomes their anchor. Grit becomes their shield. And the line between friend and foe grows thinner with every step.

Friend or Foe is a story of resilience, trust, and the unseen battles fought in the human heart. When the enemy hides in plain sight, the greatest danger is believing the wrong person.
