The planet of Caliban exists much as it has for thousands of years - the knightly orders protect the common people, fighting back the beasts that lurk in the depths of the seemingly endless forests.
Young Zahariel and Nemiel aspire to join the greatest of the orders, led by the example of mighty Lion El'Jonson and his vision of a peaceful and unified world. But the coming of the Imperium brings new concerns and a new destiny for the Lion as part of the Great Crusade, and the sons of Caliban must decide if they will follow him to glory among the stars.
An epic fantasy adventure
This is a great break in stride of the Horus Heresy series. It has great character development, a good story that instead of delving into the grim dark of the 30th millennium starts us off on Calaban, a almost feudal age world. More then 60% of the book is based here, this gives us time to flush out characters and personalities. This is a drama filled book with adventure, action, mystery and a ending that will leave you a little sad, wanting to know more.
If you are a fan of Sci-fi, you will probably like this book, if you are a fan of fantasy, you will probably like this book. If you are a fan of both, you will love this book, this is not a book to be skipped over in the Horus Heresy series.
