The Colombo Family Duet
Format: Kindle
Another amazing mafia romance duet! Widowed Brie "Breezy" Colombo teams up with a reluctant Dominika "Nik" Kusek to try and solve her husband's murder. Nik is tasked to be Brie's bodyguard as they dodge hit men, play in mafia politics, and look for any clues that could lead them to a killer. There was action, mystery, loyalty, betrayal, passion, lots of steam... it was all around awesome! I breezed through both books in one day!

Great Story.
Format: Kindle
I really enjoyed the none stop action and the thrilling suspense of who killed Terry Colombo as well as who put out hits to kill Brie. Also liked the simmering romance between Brie and Dominika "Nik" Kusek. I was little disappointed that there were no specific detail of there height just vague description. Though it did not change my opinion of this story, or the number of stars given. I found this story very entertaining and exciting to read. I can't wait to read what happens next in book 2. I whole heartily recommend this story to everyone that loves a little danger with their romance.

Yet another good story.
Format: Kindle
These Mafia stories just keep getting better. I love this author’s ability to take the reader inside the inner workings of Mafia life. I never know what’s coming around the next corner, and that makes the mystery and intrigue that much better. It certainly doesn’t hurt to have steamy scenes as well. 🔥👍 I’m looking forward to reading the next book in the series. Nicely done…read this author’s books!
