10 doubloons for spellbooks, same as ever, and 15 for the rarer ones. Any topics you have in mind? I'm not so sure about flipping through what's in the chest in the back room of the shop, but I can risk a finger or two if there's money in it. I think I may have a companion book to the last Animagi book I sold you, or at least one with a animal of some sort on the cover.
