When I was a youth, and part of the Science Fiction Book Club (Still a Thing! Impossibly Still a Thing!) I ended up with an omnibus edition of Robert Asprin's first few Myth books.
[Side note: I really do miss those omnibus editions. They still pop up in the SFBC (which I'm not part of any longer) and some older books get reissued in that format (as for instance Glen Cook's Garrett Chronicles) but mainly you're on single books now. Mostly, I think, because the era of skinny books easily compiled into an omnibus is mostly over? Anyway, I miss them.Now, back to the reread.]
I thought, as a 12 year old or whatever, that these books were the best. They were kind of silly, but kind of violent, too: like Xanth with a more adult sensibility, I guess? By more adult, I mean the sexiness was more literal than implied and slightly grotesque (Piers Anthony might have issues. He might not, but...there's a lot of smoke for there not to be any fire, you know?), the violence was brutal at times, the jokes were still mostly puns but they were more clever, more pop cultural. Which of course means they're terribly dated now, where Xanth's puns, while awful, still make perfect sense in the main.
The Myth books, to sum up, are about a human youth who is apprenticed to a wizard and not very good at being an apprentice, and then, through a series of mix ups and practical jokes, ends up apprenticed to another, different wizard from a different dimension, of which there are many. The books involved the characters trying to make a living (growing competency of the apprentice being a major plot point; his master has lost his powers but still has his knowledge and his reputation, and they have a cast of secondary characters of all sorts, cohorts and opposition and sometimes both.) As it went along it became burdened with too many odd bits and bobs, too many jokes that grow very tired. But the first book is kind of zippy, and if you ignore the real groaners of jokes, it works all right.
Fully adult me doesn't really like it that much, though. It's goofy, is the problem. Too goofy but not funny enough. It wants you to laugh, it really does, but it's like a bad kid's party clown: here's a joke, are you laughing? No? Well, here's another? Is that a grin I see, kind of? Well, all right, let me do that thing again. Why aren't you laughing?
The magic actually isn't bad, the main relationship (if I remember rightly) grows in depth, and the books become about growing up and making your way in the world, though that theme is explored very briefly in each book, so that only time allows it to become meaningful as you read six or eight books and get to actually dig into that.
I can't bring myself to read any more, though. Twelve year old me is saying I should, because I have good memories, and some problems like the ladies being mostly just arm candy get a little better as the series goes on.
If the internet can be trusted (it's can't, but I'll let it slide this time) the series never ended. Asprin kept writing more books until he died, and there were plans for more at that point, at least one of which was written by another author he worked with on the last couple books he wrote before death took him. I stopped reading some decades ago, which puts me rather out of the loop, though almost all the books written were written before I stopped reading; his output slowed greatly as he got older. I can't imagine the effort needed to dig through all that mass of books. Fortunately, I don't need to, either.
