...and the excutive editor being a "well-known" published author (and I would argue the use of well-known here), I see no meaningful editorial experience among them.
I would ditto that argument, sorry to say. "Well-known" is something it's extremely difficult for writers to be; there are very few writers out there who are actually "well-known," IMO, and most of them turn up way more than >6000 hits when Googled. In fact, most authors I still wouldn't consider "well-known" show a larger number than >6000 when Googled, and have autofinishes set up on Google, too.
That author has an excerpt of her book on her site,
which is also on the Hellfire site. It has...problems, with grammar, punctuation, and style (including misused/incorrect dialogue tags).
So it seems the errors do not only exist in bios, where you might think the editors in question were simply typing quickly or not proofreading as carefully. (And for that reason I chose a book by one of the editors to link to, rather than an author whose work may have been made incorrect by the editors through no fault of their own.)
So, yeah...newbie micropress loaded with language/grammar/punctuation errors, and an editorial staff unaware of those errors? I'd give it a pass.
