The Incomplete Book of Dragons (UK), also known as The Complete Book of Dragons: A Guide to Dragon Species in the US, is a book featuring all known dragons from Cressida Cowell's book series. It was released on May 20, 2014.
Long ago, the world was full of dragons. But what happened to them? Where are they now? These pages are taken from the notebooks of Viking Hero Hiccup Horrendous Haddock the Third when he was just a boy. A keen dragonwatcher, Hiccup paints a picture of the brilliance and fire and spirit of that lost dragon world. Featuring dragon profiles, dragon anatomy, dragon riding tips and lots more must know info e.g. how to spot the difference between an arsenic adderwing and a glow worm (you don't want to mix those two up) and what to do when confronted with a Hellsteether. This is a must for all keen dragonwatchers out there.
The book tells a short introduction to the dragon, the speed, the size, the fear factor, attack, and disobedience of the dragon and mostly shows a picture.
On the front and back cover, there are a few unknown dragons not featured in the books or shown on TV.
If you look closely, you can spot the difference between the dragons that are made up for the cover and other dragons (like the colors).
