Merciless by Ella Frank

He was sent to watch me. Now he can’t look away.

They sent the president’s son to babysit me.
How precious.
Shepherd “Shep” Winchester III thinks he’s here to keep me in line—keep me quiet, keep me still, keep me safe.
Good luck with that.
I’m Theodore “Theo” Rinaldi, the youngest Prince of Monaco, and the most merciless of the Park Avenue Kings. And I don’t do obedient. Not for my royal family. Not for the crown. And definitely not for the suit King sent to shadow me.
Shep is all discipline and duty.
I’m chaos in a custom suit.
We clash. We combust.
And then we cross a line we can’t uncross.
Now there’s a blackmailer on our trail, a target on my back, and the Kings think I’m the traitor. But if they want to come for me, they’ll have to get through him.
Because the soldier with the perfect posture and the unreadable eyes?
He’s not just protecting me anymore.
He’s falling for me.
And I’m going to ruin him for it.

Merciless (Park Avenue Kings #4) is the first book in a duet within the Park Avenue Kings series. Ruthless (Park Avenue Kings #5) will be the continuation.
