Out of Spite, Out of Mind (Magic 2.0 Book 5) by Scott Meyer (Kindle)
Decent mind candy as usual. He takes a fun premise (a secret computer file that contains reality, and can be edited, so some people find it and make themselves magicians) and plays with it in amusing ways.
I’m hoping at some point that he starts cracking into the mystery of the file. But maybe he’s going to milk this for as many books as he can before a Big Reveal. Or maybe he hasn’t thought of the Big Reveal.
At any rate, if you like the first 4, you’ll like this one just fine.
