If you follow the magic lesson path with Cassandra, she will eventually gift you a spellbook of your own. It is near the end of the lessons though, so it takes a while. Good luck!
ah okay, now that you mention it, i think i remember that on one of the other endings but had completely forgotten about it. thanks, i would have spent forever waiting if you hadn't mentioned that! I've almost completed all the endings, so looking forward to seeing this!
