I was promised a roller coaster ride of suspense and O'Sullivan did not disappoint. Lots of action. Warning - don't start this before bed or you'll be up all night reading.

5.0 out of 5 stars Anticipation........Cannot wait

Reviewed in the United States on July 8, 2022

After reading Romance Under Wraps written by Claire I am hooked. Cannot wait to read Rules of Engagement!!!! This author is one that will take you on a journey you would never expect. Danger, romance, excitement and wit. Cannot say enough about her.
Finished Rules of Engagement and was an exciting and thrilling story. Suspenseful, exciting, and so real. Fit the current state of affairs. And I have to say.......the ending was totally unexpected but knowing Claire I was not surprised!! But amazed at her endless ingenuity.

5.0 out of 5 stars Cook, Fleming, Clancy, and Jesus in One Novel

Reviewed in the United States on December 27, 2022

“We’re sending you to a desert island.”

“As long I can bring something to read. I’ll pack my Robin Cook novels because I love medical thrillers. James Bond and Jack Ryan collections for action and suspense. And some romance stories…”

“You can only bring one book.”

“Ok. ‘Rules of Engagement’ it is!”

You can have it all in one book—hard action, tender romance, claustrophobic thriller, global conspiracy. A beautiful scientist with a past meets a commando who loves the Lord, putting America, Israel, and their hearts on the brink. Rules of Engagement means no rules for plotting billionaires, ruthless terrorists, or two star-crossed lovers charged with saving the world!

5.0 out of 5 stars Terrifyingly Realistic

Reviewed in the United States on July 3, 2022

Seemingly right out of today’s headlines, “Rules of Engagement” engaged me in a tormenting, fictional revelation of a diabolical plan to depopulate most of the world through a pandemic, the spread of a deadly Ebola virus. This action packed thriller uses realistic violence to forcefully defeat ‘the bad guys’. The author is brilliant in the skillful use of scientific, military, and medical terminology, while bringing home the meanings and inferences to my level of understanding. The novel is politically savvy with uncanny revelations.

The characters are well developed. I would like to see Scott Walker and Cheyenne Keyes ‘deployed’ in a follow-up novel. Scott and Cheyenne’s attraction to each other has lots of friction, reminiscent of the Bogart and Bacall classic movies. “Rules of Engagement” is a shocking suspense thriller, well detailed, excitingly timed, and technologically accurate.

When I finished the novel, I realized that I’d found the missing spark of excitement which had vanished with the deaths of authors, Tom Clancy and Vince Flynn. If you were a follower of Clancy or Flynn, I’m sure you’ll love this book, too!
