I grabbed Battle of the Linguist Mages from the library the other day (thanks, Libby!) and it wasn’t bad. It’s enjoyable reading Ready Player One from the anarchist point of view, even if it’s a bit broad. Don’t look for well-architected laws of magic here or anything — it’s more that a bunch of stuff happens in ways that amp up the fun factor.
But it’s really fun! The role of punctuation is top-notch and had me pausing midway through to do some Web searching.
