This collected edition bundles the first three books in English into a paperback volume. The size and printing are the same and it has all the extras at the back. The paperback nature means the large spine will crease almost immediately but it will open fully allowing you to read the centre pages with ease.
It isn’t as nice as the hardback volumes but it is much more portable and affordable. This is an excellent introduction and means you won’t be waiting for the next book after the cliff-hangers of books one and two.
The extras are contained at the back and there is the handy family tree at the beginning to remind you who everyone is and how they are related.
