The Trachanoids are a new kind of hero for kids 5+. With the opening of the book you see selfish, "me" oriented dinosaurs - more intent on serving themselves and being demanding and angry toward others. By the end of the book the dinosaurs and the humans on Earth have learned to work together and help rid the earth of the Mugo - alien 1/2 wolf 1/2 crocodile creatures who spend their time attacking and taking over other worlds.

The book is a great introduction to science fiction for kids and a fun way for them to learn character and the importance of working together. Well written, entertaining and fast paced - you'll see your kid's imagination get moving when you read this book.

This book comes 2 ways: One as a hard bound book complete with color pictures and the other is a small chapter book of 64 pages with black and white pictures. Personally I thought the hard back was rather hard to read and it was very wordy with tiny print for younger children who are being read to. The pictures in the book are wonderful and kids will enjoy those though. I thought the chapter book was ideal for kids 5+ whether they are being read to or doing the reading themselves. The text is large which is ideal for beginning readers who are able to read fairly well on their own and reluctant readers should enjoy reading this also with the fast paced, action packed movement of the story.
