Now she’s back and this time I won’t fail her. I’m ready to put it all on the line to keep her safe.

Customer Reviews


What an amazing end to a duet. It was fast paced and bloody. Mathias and Gemma are hot yet emotional. Nice job Mrs Malone. I highly recommend this book. You won't regret it.

Love Bonds Strengthen Us

Mrs. Malone had me all teary eyed by the end of this book. It was truly a wonderful conclusion to Matthias and Gemma’s story.
Sinful picks up right where Sin had left off.
Matthias leaves to keep his family safe and also to eliminate the people posing a threat to them. He’ll be going into the lion’s den alone and the chances of him surviving are small but it’s a sacrifice Matthias is willing to make.
What Matthias doesn’t realize is how much he is truly loved and that his family will stop at nothing to protect him, even if that means protecting him from himself.
Will they be able to find Matthias before it’s too late and come up with a plan to defeat their enemies?


I am shocked. I did not see that coming. And I'm pretty sure you won't see it coming either.

How do you write a spoiler-free review when all you want to do is gush over the twists and turns that happened in the book.

I do not know how Malone squared will top this duet. And who in their right mind allowed JJ to have a gun? I mean, are you out of your bloody mind?
