Do you mean this
Mithra Publishing?
Their website looks to be misleading: they say "Could you join this Hall of Fame?" and have photos of authors like Danielle Steele and JK Rowlings. It implies that those authors are part of Mithra, which is patently not true. (If you click on the photos, it takes you to a Turkish website.)
Their business model is...interesting. They get their revenues not from selling books but from selling advertising space in those books. I'm guessing that if someone was willing to cough up £1200 for a one-page advert in a single ebook title, they wouldn't be too choosy about the product in question. It's not hard to imagine how this could go wrong. Like, say, advertising dildoes in a Christian romance novel.
They don't seem to do much editing, as they say that contracted books get published within two months. They also offer a service where they will convert a manuscript to e-reader format (for £350, which sounds like a lot to me).
What I don't see is any evidence that they know how to publish books or sell them to readers. They only list two authors as being contracted to Mithra, so either they're very slow or very new.
