What are the first 100 pages of Warriors the fourth apprentice?
You can look at Harpercollins.com. Just type in warriors and looked for the Fourth Apprentice.
Nowhere, yet. At least not completely. I would suggest looking on Warrior Cats Wiki. Just search it exactly as I did in the Google search and it'll come up as Warriors Wiki. Go to amazon.com, type in warriors, the fourth apprentice, and click on look inside. Prelude and first pages of chapter 1 included.
