Cavaleiro Do Drago

Dragon Rider is about a brave young dragon called Firedrake who embarks upon a dangerous journey to the Rim of Heaven in the Himalayas--a magical place where silver dragons can rest easy, free from the threat of destruction by mankind and their only hope of sanctuary. The key to its location is a map rendered by a rat who is a master cartographer.

It is a great book for kids over age 8!
