It was in the featured New & Hot in Fantasy Fiction.
Oh, cool!

P.S. Does Planeswalker: Agents of Artifice rely on knowing anything about Magic?
Not really. There are a few references/names that won't mean as much to newcomers, but they're few and far between (and also unnecessary to enjoying the book). It was, in fact, deliberately and specifically written as a jumping-on point for people new to Magic, as well as to appeal to existing fans. (In point of fact, I was basically a newcomer when I got the gig; I'd only ever played magic a couple of times, and hadn't read any of the fiction. They specifically wanted someone new, who wouldn't feel bound to reference or build on any of the previous fiction. Though I did fly up to Seattle for a full-day meeting and basically a "crash course" in the basics.)
