I just bought and read an Angry Robot book after reading a glowing review on Tor.com's Facebook page. It was not a good experience.
It wasn't totally amateur hour, but the book desperately needed developmental editing, and my interest kept wandering to the point that I made a list of basic copyediting mistakes. I don't claim I only read books with no mistakes, but I do claim that if a book keeps me well involved, I don't notice the mistakes.
The most obstreperous was misspelling "whoa" as "woah." In a contemporary story using a younger character's POV, that might be excusable or even make perfect sense. Unfortunately, this was a fantasy set in a medieval-style world. To me, that means whoever was running the spellchecker must have told it that "woah" was a correct spelling. I'd say that's a failure of editing, and it wasn't the only one.
I won't bore you with the rest of the list, but I won't be buying another Angry Robot book. Just a data point for those authors trying to decide if Angry Robot will publish their books up to a standard the author is willing to accept. It wasn't terrible, it was just disappointing.
