I had to read this book for 11th grade English. Most people in my class didn't like it because they were cry-babies and didn't like the small font and amount of pages. If you are one of those people, don't read it. You don't have anything to prove. But if you do like science or paleontology, you will love this book!

9/10

Scientists, an eccentric old man, a paleontologist, an archiologist, a mathematician, and two kids. Exciting on the edge of your seat thriller. Suspenseful and with a good plot. This book is a page turner, with you wanting to read more quickly to find out what happens to the people during the story. The beggining is a bit slow but definitly worth reading through once you get to the action.
