"Skeeve, a magician's apprentice and wannabe thief from the dimension Klah, tries to learn the basics of magic from Master Magician Garkin for several months but to no avail. Skeeve can do little more than float a feather or light a candle using magic."
Here we have a nice, normal apprenticeship... until the Master dies (it's not too much of a spoiler! One of the summaries I read totally had that in there!) and Skeeve is left with a demon to get revenge... who also kind of ends up being Skeeve's second Master, in a way.
Sadly, this book focuses more on revenge than the education, but from what we can get out of it, there are a few important details that help this timeline quest.
First, it seems as though Skeeve wasn't doing too well as an apprentice. As I've looked at in previous posts, this could be due to that whole idea of peers, and how they help you out in learning.
Or, you know. Skeeve could just be really bad at what he does.
Either way, the apprenticeship dissolves, leaving Skeeve to navigate the world without all the knowledge he needs to succeed.
I'm not sure what that says about magic school, but it doesn't seem to be offering glowing praise of apprenticeships, either.
