Ruthless: Park Avenue Kings, Book 5

Summary

They called him America’s golden son.

Now he’s the man who’d burn the world for a prince.

When Prince Theodore Rinaldi vanishes, Shepard “Shep” Winchester III will do anything to bring him back.

What starts as a mission of duty ignites into a forbidden obsession—one that blurs every line between loyalty and love.

Back in New York, the Kings are under attack, their secrets exposed, their brotherhood fractured. And when an attempt on Theo’s life plays out in front of flashing cameras, the world sees what they were never meant to: a touch too intimate, a look too raw.

Shep is the son of American power.

Theo is European royalty.

And in a world built on loyalty, betrayal, and lies, love might be the most ruthless act of all.

Ruthless (Park Avenue Kings #5) is the second book in a duet within the Park Avenue Kings series. Merciless (Park Avenue Kings #4) is the first and should be listened to before Ruthless.

Books 1-3 can be listened to as standalone novels.
