Think of it like a mosaic. Each book is a beautiful, complete tile. If you look at them one by one in any order, you appreciate each picture. If you step back and look at them in sequence, you see the larger, interconnected artwork. Both perspectives are valid and rewarding. Your first time through, you might focus on the individual tiles. On a re-read, you might appreciate the bigger picture. There's no single correct way to view a mosaic.
