The Ruthless Guardian's Obsession: A Forced Proximity Dark Mafia Romance

Rate this book
AMAZON BESTSELLER in Mafia Romance & Enemies to Lovers Romance ⭐

I went undercover to find my brother's killer, but the brooding, battle-scarred head of security pinned me against a wall and ruined me first.

Luca Morelli is silver-streaked, lethally protective, and loyal to the mafia family I suspect murdered my brother eleven years ago.

He's cold commands and dangerous restraint. I'm sarcasm wrapped in secrets that could destroy both of us.

Then everything explodes.

We're on the run together—hiding in the dark, his body pressed against mine, his mouth swallowing my moans while enemies hunt us outside.

He tends my wounds with hands that have killed. He looks at me like I'm worth burning his whole world down for.

Luca makes me beg before making me shatter. His touch has me forgetting why I came here in the first place.

By the time I realize I've fallen, I'm already drowning.

But someone is watching.

Someone knows exactly who I am.

And when my secrets come out, the man warming my bed will be my executioner.

This can be read as a standalone novel with a guaranteed HEA!

confused

okay,i really liked the vibe of this book. the characters were very interesting. i was immersed in the story, and then, events strained credulity.
they were captured, bleeding, injured, but then like super hero’s managed to escape, evade capture and act like they had no injuries. there were several repeats and oopsies.
he loses his suit jacket in their escape, then several chapters later, he’s wearing it. his ribs are broken, but he jumps over fences like superman.
he tells her his origin story while they are hiding out, then at the end of the book he tells her his origin story again and she acts like she’s just hearing it.
there were a lot of inconsistencies in this book.
it’s a shame, because i really liked the storyline. this Author is talented but really needs a new editor to catch all these glaring errors.
