They're obviously very small, and it doesn't appear from their "About" page that they're regularly stocked in bookstores.
But the covers are fantastic, and I recognize a few of the names on their Author list. Simon Wood, who I know a bit, is a sharp, good guy, a good writer, so his presence there is a point in their favor for me. (Which doesn't mean I'm recommending them or anything.)
It looks to me a bit like a small "more for the love" outfit, but it looks like they're at least doing it professionally and well. Looks like they've been around for a couple of years, too, which is good.
I read inside their bestselling book on Amazon. The editing was not up to commercial standards, and the book was ranked around 120,000. However, they may do very well in their niche, and it's possible their target demographic is perfectly willing to put up with the grammar and punctuation errors.
