Succession in Las Vegas! From bestselling writing duo Karen Mack and Jennifer Kaufman, a sexy and suspense-packed thriller about the prodigal daughter of a Las Vegas casino empire who returns to take over her family business, only to discover that she’s up against the Mob, the Feds, and her own brothers.

When Josie King left Las Vegas in the 90s, she never looked back. The daughter of gambling mogul Roy King, spirited math whiz Josie grew up on the casino floor but deliberately turned away from the family business. She’s been living a quiet life in LA as an accountant and a single mom when she finds herself summoned back to Sin City. Now, fifteen years later, her father has died unexpectedly, and Josie’s siblings are already gathered for the reading of his will...only to discover that in order to inherit they must spend three years working together at the notorious family casino, The Jackpot.

Josie’s pride won’t let her walk away from the family empire again, so she agrees to take charge of the casino’s finances. She quickly discovers that while Roy King was once the most powerful man in Vegas, times have changed. These days, everyone has a piece of the Josie’s brothers, the FBI, the local mobsters, even the sexy rival casino owner who’s more than a friend. Las Vegas is more dangerous than ever, but Josie knows that to save the family business she’ll have to wade in deeper…

Stacked with sex, crime, sibling rivalry, and mountains of cash, The Kings of Vegas is an electrifying thriller with a tough and irresistible heroine at the center of the action.

“Moe cut him off: Don’t talk. Don’t think. Just do what the —- I tell you. Are we clear?”
“What is this, Hitler Youth?” Sam muttered.

You’re kidding right? You are absolutely kidding? Why is this line of commentary, regardless, if it’s a joke or not, or a sarcastic comment from one of your characters/ inside of this book? Either you live under a rock or you’re ignorant. This is completely inappropriate for given the state of the world and the current climate we are in.

I digress; my book review continues down below.

The author either watches cop/mafia shows and his visited Vegas enough times as tourist to be enamored with the idea of glamorizing the seedy parts of Vegas or lives there and hates it. This book needs to scrapped or revised its rough. It’s crude and the sex scenes are not even sexy. It just the FMC being a mean, pick me girl as an older adult women. She’s mourning her dad who died, chooses to have sex on his office desk at his funeral? The scene isn’t even funny or hot. There is basically zero chemistry between characters. The only thing the plot had going for it. The reader is quickly shoved into a messy murder, kidnapping, embezzlement plot and romance takes a side set. The main character, Josie, basically contradicts her self every other chapter saying she doesn’t wanna live that way anymore, but then continues to live that way and foster that mafia Vegas lifestyle. It doesn’t make sense.

“Josie had made a point of turning the bedroom into a preteen paradise” …
“… far to expensive for twelve year old….”
“I’ve seen five-year-olds there. Are you taking Billie? She’ll love it.” Sam said. “They also have archery, but that’s for Girl Scouts and pussies”
“ When Billie woke up, Josie had told her that she had changed her mind and they were going shooting”
“Yes. An actual gun. This is Nevada, kiddo”

Your preteen, who the main character continuously states that she does not want her child having the same rough gangbanging trial that she had, you take her for shooting lessons and to familiarize her with guns. You let your child be around another child who is involving herself in criminal behavior but that’s okay because that other child’s mom could help you babysit. To top it all off there is a poorly written two page climax about a kidnapping scene that reads as if you only ever have seen something similar on law and order.

I genuinely stand by my opinion, that this book needs to be revised and or taken a different direction. There’s not a lot going in this book that I enjoy.

I found this book to be mildly interesting as a saga of a family involved in casino operations in Las Vegas with ties to the mob. There is a lot going on with a mostly dysfunctional and feuding family—- drugs, alcohol, romance, intrigue and theft. It was of particular interest to me since I was a former CPA involved with hotels and casinos and it was my staff who uncovered the fraud with the scales perpetrated by the Stardust hotel. I thank NetGalley and Harper Collins for the opportunity to read and review this book prior to publication.

The Kings of Vegas was an okay read but it never fully grabbed me. The story is readable and the Vegas setting is interesting, but the characters often felt flat and the plot predictable. There were moments that entertained me, yet overall it lacked depth and tension. It might appeal to some , but it did not leave a lasting impression other than some down right ICKS


Thank you to NetGalley for the ARC in exchange for my honest review

Shades of Harold Robbins. I would rate this 3.5 stars if half stars were allowed. The Kings in the title refer to the King family; the now deceased father founded the Jackpot casino in Las Vegas. It is now up to his five children to keep it going. When one of them gets into deep financial trouble, he goes to the Mafia for help. Josie, the youngest sibling and the book’s protagonist, returns to Vegas and attempts to make sense of the Jackpot’s errant operation. With her knowledge of forensic accounting, can she help right the ship and defeat the mob? The story moves right along with a few hiccups. The way everything is tied up at the end may seem a bit pat, but it worked for me. A good read. Thanks to NetGalley and Harper Collins for providing me with a review copy.

I received a free copy of, The Kings of Vegas, by Karen Mack; Jennifer Kaufman, from the publisher and Netgalley in exchange for an honest review. Josie King is back in Vegas, but not by her choice, her father has passed away. Josie King is back in the family business of gambling and casinos. I did not care for this book at all.
