4.5 stars

Lethal Game was such a good read, an excellent addition to the Red Stone Security series.
The storyline and characters captured my interest from the first few pages and keep me up late into the night as I couldn't put it down.

I love this series, each book can be read as a standalone, each book has been a page turner and each couple has entertained me with their love story. Katie Reus is a talented author and I highly recommend this series.

Isa works for Red Stone. She goes into companies and checks their security. Graysen is former CIA and was undercover when he met Isa a year ago. He posed as a defense contractor and was working to take her father down for selling the identities of other agents. Her father is killed and she leaves D.C. and goes to Florida.
Now Graysen comes to work for Red Stone and aims to get Isa back. She can't forgive him for lying to her. They are teamed up to go undercover at an aeronautics company. They are trying to find out who's stealing money from the company. When they are trapped in the building with Russian killers, they have to save themselves and two friends who are trapped with them. Will she forgive him and give them a second chance?
A really edge of your seat book. It also tells the story of Emerson and Carlito along with Isa and Graysen. Two love stories in one. Sex. Russians. Action.

Please tell me it isn’t so, Lethal Game is the final book in the Red Stone Security Series. Katie Reus has given us readers action-packed romance series and none is more so than Lethal Game. As Ms. Reus has done in some other of her books we are given two romances within one novel. The main couple is Isa and Graysen, who have a history. I must say I like How Isa made Graysen work to win her back. It is as much a last chance as it is a second chance for Graysen. Then we also are given Carlito and Emerson relationship story too.

The grand finale in the series has the strong protective male and the independent just as capable female working together to survive the danger and bring down the bad guys. Love her heroes and heroines in this spectacular book.

I liked parts of this book, but for the most part, I was missing too much information to truly enjoy it. I missed the fact that it was the final book of a series when I requested it, and had I known, I probably would have passed. I feel that this book is definitely not part of a series that should be read out of order. I was missing a lot of background information, including details of characters that were introduced as if I should already know who they are. Because of this, I was more drawn to the secondary romance of Emerson and Carlito, whose romance didn't require as much introduction. I greatly enjoyed reading their romance, and if the book was only about them, my rating would be much higher. Due to my ignorance of the previous books in the series, I was unable to become invested in the romance between Graysen and Is a. I was too busy being confused about what the heck was going on. It's a shame. I will try out the first book in the series, hopefully that will improve my understanding.
