Edge of Extinction #2: Code Name Flood by Laura Martin

My name is Sky, and my friends and I are trekking through lands full of vicious dinosaurs to deliver a critical message somewhere to the middle of Lake Michigan. We've discovered a lab at the bottom of the lake that is actually breeding more dinosaurs! They say it's necessary to balance nature, and we're beginning to understand their thinking. However, the message I was carrying revealed the Noah's plan to eliminate all dinosaurs using nuclear bombs which will also kill all humans living on the surface! Somehow, he discovered the lab's location and bombed it, killing my best friend Spencer. There may be a way to stop the Noah from destroying the world, but I will need to get past his soldiers to enter his compound. But how can I travel a hundred miles in a day without becoming a meal for thousands of dinosaurs.

This book is the second in the series, but I didn't read the first book yet. I suggest you do, since it would help explain the situation and the layout of the world. It sounded like humans used DNA to bring dinosaurs back from extinction, but the dinosaurs carried a disease killing most of the people on the planet. The surviving humans created compounds in different areas but had little contact with each other. The plot was full of adventure, action, and suspense with the Noah's army searching for Sky and her friends. Dinosaur lovers will enjoy the book, as it blended information into the plot. Chaz was a girl working in the lab before the attack, and she informed Sky's group about the dinosaurs they faced. For science lovers, the whole concept of the conflict stressed the importance of letting the environment keep itself balanced without human interference. Predators and plant-eaters would keep each other's populations in check, and humans could co-exist among them. The author found a way to include "monsters" in his story without inventing new monsters. The book was a fun blend of dinosaurs and modern technology, and I recommend you give it a shot.
