‘Relentless’ by Mark Greaney. It’s like a high-octane action movie poster had a baby with a travel brochure. We’ve got the silhouette of a helicopter against a turbulent sea, and then—boom!—a sharp cut to a cityscape with a guy running down the street. Is this a spy thriller or a promo for the new Mission Impossible movie?

The title “Relentless” in big, bold letters. Yeah, we get it, the book’s not about a leisurely walk in the park. And then there’s the quote from Lee Child. You know it’s serious when the king of action thrillers himself gives a nod. The color contrast is so intense, it practically screams at you to pick it up.

So, if you’re into fast-paced, heart-pounding chases and can handle the visual assault, this cover promises a wild ride.

**Rating: ★★★★☆ Summary: “Relentless” by Mark Greaney features a cover that’s a dynamic blend of intense action and dramatic imagery. Perfect for fans of high-stakes thrillers who enjoy a visual punch.
