Ex-army Ranger Michael Stewart never intended to become a CIA operative, but life had other plans. Now, he stays forever in the shadows, unseen and unheard, moving robotically from one dangerous mission to the next.

Ultimate thrill.

This is easily one of the best stories I’ve read recently—I devoured it in just two days, completely unable to put it down. C.M. Rachels blends pulse-pounding action, mind-control science, spies, touches of the supernatural, shocking twists, and a forbidden romance into a mind-blowing thriller that demands to be read in one sitting.

Ruby and Michael are unforgettable leads—both broken yet strong, resilient, and tied together by undeniable chemistry. Their dynamic carries the story, making the emotional stakes just as gripping as the physical ones. The book gave me the same kind of vibes as Stranger Things mixed with The Winter Soldier: dark, intense, and action-packed from start to finish.

By the final page, you’re left breathless—and with the sense that a sequel may be on the horizon. Highly recommended for fans of thrillers with a supernatural edge, complex characters, and non-stop momentum.

I was pleasantly surprised by this book. It’s really good. The story has depth and plenty of action, and the characters are not only relatable but also likable. It’s not like your other spy novels. This one combines spy, paranormal, and romance elements, and it all flows together in a way that works. I can’t wait to read more of this series.

This book kept me turning pages late into the morning. The characters were relatable, and the story world was well-built and immersive. I’ve always been a fan of super-soldier novels, and Her Blood Calls had me hooked from the first page. The book is a standalone, but it’s part of a series, and I can’t wait to read the next book.

Secrets, Sparks, and Second Chances

This fast-paced story hooks you right away—mystery, romance, and danger all rolled into one. Ruby’s got no memory, Michael’s got too much past, and when their worlds crash together, it’s one wild ride. Twists keep coming, and the chemistry sizzles. Great if you like suspense with heart and a touch of action-packed drama.

This gripping romantic thriller that delves into the covert world of espionage and secrets. This novel combines romance and thrilling suspense, making it a heart-pounding read that will keep you guessing.

[Bella Nicholson · Rating 5 out of 5]

Her Blood Calls by C.M. Rachels accomplishes its mission with flying red, white, and blue colors. It’s post-Cold War espionage with heart-pounding action and a non-stop, intense romance.

Michael Stewart is the protagonist who falls in love with a “civilian,” and her lost memory could cause everyone a whole lot of problems. At first, he has to find her, and when he does, it’s an explosive situation. Once these two spark, they sizzle.

She’s the reason for much more than any mission. Everything turns upside down: the mission, the past, the truth, and the bad guys who are closing in and that's where Rachel excels, Stewart kicks butt with very descriptive action scenes.

Watch out when you pick this one up. Once you start reading, you probably won't stop until the last page. It's fast-paced well-plotted, and will control your mind almost as much as one of the twists in Her Blood Calls.

[Suzanne · Rating 3 out of 5]

I don’t know what I just read. The premise of this book is what interested me, but the story was a bit disjointed. In the end it’s about found family, but I don’t think the relationships at the end were earned through the story. There were some odd connections that still make no sense to me.

I also feel like there was a lot of repetitive story beats and even dialogue. It kept my attention, but I just don’t know.
