His Ruthless Heart

Rate this book
I always swore I'd never cross that line...
But it was a lie.
Lina was always meant to be mine.


I was born into blood and violence.
Clawed my way to the top.
Now I have a new title—and a new territory to rule.
Every inch of it... and everyone in it.
I don't do weakness.
I don't do soft.

Except for Lina.

She's been my best friend for fifteen years.
Always too young. Too sweet. Too off-limits.
But when she needs my protection, I'll do anything for her.

Even be her fake scary boyfriend.

Twisting her up in my world shouldn’t save her.
But I’m starting to think my shortcake doesn’t want saving...

She wants me to corrupt her.
And I'll gladly drag her into my darkness.


Read on A sizzling, protective mafia romance where her lifelong protector falls first—and fake dating turns dangerously, deliciously real. The lines they swore never to cross are blurring, and threats are pushing them closer to admitting the she was always his.

Ace and Lina will steal your heart!

Swoon! I really loved this book – the fourth in the series! The story, the characters, the action – everything was amazing! Ace is Mafia – a Capo in charge of Syracuse, under Luca. Lina is his best friend since elementary school. The one pure, joyful constant in his life. Everything stayed platonic for years – even if they both secretly harbored feelings for one another. Ace thought she was too innocent for his world to taint. Lina thought he was too far off her league. But one incident with a few of her art classmates led to a “fake-boyfriend” deal. But fake is far too real – feelings can’t be contained for long. A rollercoaster of events occur. Ace has to face trouble regarding his dominance in his territory and Lina finds herself in the crossfire. But there is nothing that can stop these Mafia men when it comes to the protection of the women they love! Ace was PERFECTION – his heart IS ruthless, but to everyone else apart from Lina! And Lina complements him so well – she is way tougher than he thinks she is! My favorite in the series so far. 5 stars!

Ace and Lina

These two knew each other from childhood. He saved her from being bullied about her art. Ace became her self proclaimed protector then into adulthood.

Years later they are still the best of friends, him a man with her known name and reputation and her an undergraduate art student. Ace is still playing the role of protector even though he wants more. Lina is allowing herself to be protected even though she wants more.

One day, Ace comes up with the scheme of pretend boyfriend to keep unwanted attention away from Lina. Eventually the line get blurred between pretend and real. Will their friendship get beyond their doubts.

I enjoyed reading this addition to the series. Ace was introduced in a previous book and now he has his own story. Communication, truthful communication is what was missing between Ace and Lina. Their behavior towards each other clearly pointed to their attraction. But, Ace saw her as good and pure and him not being worthy of her. Lina just thought he put her in the friend zone because he didn't show any reactions to her attempts of making him jealous.

This series keeps better and better. I was hooked from the very beginning. I love the books where the man is super Alpha and Dark and nothing or no one gets to him except that special woman that is in his life. Lina has grown up with Ace and he has always been her protector. When she lets him know she is getting bugged at school he becomes her pretend boyfriend. It only gets better as both of them want this arrangement to be anything but pretend. I loved every moment of this story. I could not put it down. I was hooked with as things developed this couple gets closer and closer, and the chemistry between them gets harder to deny. This is a definite must read!!! Hurry up and pick up your copy you won't regret it!!

Wonderfully Ruthless

This is yet another example of what the right person in the right situation can do and accomplish.

The support and the willingness of these characters towards each other is felt with each turn of the proverbial page. But it’s the chemistry between Ash and Lina, that makes this story so compelling.

I’m truly enjoying this inner circle of this series. I’m hoping to see more.
