Let me start by saying I'm not usually into medical thrillers, but this book? It grabbed me from the first page and didn't let go. The way Tanna, a medical student, gets pulled into this dangerous investigation when her roommate is killed felt so real - like I was right there with her.

The chemistry between Tanna and the tattooed motocross champion who helps her was electric. I loved how their relationship developed while they were literally racing against time to uncover this terrifying underground experiment. The scenes where she realizes she's been infected with a man-made virus? Chilling.

What really impressed me was how the author blended real medical science with fiction. As someone with a basic science background, I found the virus research fascinating yet accessible. The action sequences read like movie scenes - no wonder the author has screenwriting experience!

Yes, some parts required suspending disbelief (it is fiction after all), but that's what made it such a thrilling ride. The pacing was perfect - I finished it in one sitting because I just had to know how Tanna would steal those hard drives and clear her name.

That twist near the end? Brilliantly placed. It changed my whole perspective on certain events without feeling gimmicky. And while some might find the ending shocking, I thought it stayed true to the gritty realism of the story.

Warning though: there are some graphic medical scenes that might not be for everyone. But if you're okay with that, do yourself a favor and read this book. It's one of those rare thrillers that stays with you long after you've turned the last page.
