According C21Media.net, Rainbow studios another project planned besides the Winx Club, PopPixie, Huntik, etc.
"Aside from PopPixie, Rainbow has another new project in the pipeline that isn’t yet in production. With Silvia Brena (former director of Cosmopolitan Italy) attached, Maya Fox is aimed at teenagers and is based on a successful brand that already consists of a novel, a website, a blog and various magazines. “It’s dark and gothic,” says Hryniewicz. “It’s set in London and follows a fashion-conscious teen blogger who has psychic powers and is being pursued by a serial killer.”"
Ohh...this sounds interesting for those who are a little more the freaky thriller stuff.
As for the books, they're only available in Italian. As for the art style, I think it's just pure coincidence that the Winx Club is similar considering that they're both from Europe. Look at manga and anime. :)
(For those who really don't understand, people who read both manga and European comics/BDs will know what I'm talking about. BDs have a distinct style that emulate manga sometimes--like in WITCH--but are quite different from real manga. Such as colouring and lineart techniques as well as attention to proportion of bodies per panel. BDs are much looser in their art and are often fully coloured, hard-covered and printed on 10x12 inch paper--and expensive.)
