Thanks for adding the Wizard books to your All Time reading list! Seems like the right place for the GOAT.
I hope they messed together in a good way for you. They are like one big story shown through the eyes of different characters at different points in time or at least that's how I tried to make them—Mevner in the Wizard, Redwing in Dead Rainbows, and Murphy in the Space Wizards. With Melock tying them all together.
