I had read some of Novik's Temeraire series a while back, and she seemed like a good author, so I took a chance on her new YA series.
The first book was quite entertaining; enough so that I checked out a copy of the 2nd book in what appears to be destined to be a trilogy.
The Scholomance is like Hogwarts without a sense of humor, perhaps more like a Marine Corps boot camp which tries to eliminate, in this case with extreme prejudice, most of the recruits before their incompetence might kill other fighters. Or maybe it's got a bit of a deadly serious version of Clouseau vs. Cato, where one can be attacked at any time without warning.
Good fun.
