This book is about a triceratops that hatched out of a hen’s egg. It is also the only living dinosaur in the world. A boy named Nate Twitchel and his friend go on a quest to save this dinosaur. The main characters are Nate, a paleontologist, a dinosaur,and Nate’s  family, which is his dad, his mom, and his sister. The book takes place on a farm in Freedom, New Hampshire. My favorite part was when the egg hatched. The dinosaur was so cute as a baby! I really, really enjoyed this book and I would recommend this book to people who like action and times where you think “ wow! This is interesting, but I wonder what will happen next?” I would most definitely rate this book 5 stars. It is really good.
