One always approaches a second volume with some trepidation. Will it be as good as the first? Will the authors/artist maintain the integrity of the vision? Will it excite as much? And a thousand other questions large and small.
I need not have worried. It is true that the story and the characters have moved on. The story is picked up a few years on. And what we are given is a natural development - one that is consistent with the first story but which presents the world anew. The world itself has grown (although it is still the same claustrophobic, shadowed setting), but so has the perspective of the characters. This move forward has been handled well. Themes from the first book are brought forward and developed whilst introducing new elements.
The artwork is as superb as ever with pictures that invite you to study them in detail whilst the story line and dialogue has become appropriately more sophisticated.
If you haven't taken the time to look at these books, I really do urge you to get them. The production equals the content and they are books that you will treasure.
