Some questions on a Friday

Some questions I have been posing over on the ol' twitter as of late and wish to ask in a more extended manner:

1. Does anyone have any recommendations, or know of, any work that would/could be categorised as 'chick lit' while also dealing with a heroine or supporting character's chronic illness? Not something like cancer (which does feature in quite a number of books) where there's room for either a tragic death or an improvement in one's condition, or mental/psychological issues like addiction or depression which can involve definite 'improvements'? I've been thinking about the genre and the way in which so much of it is a kind of coming-of-age or discovering of identity, but it strikes me that while chronic illness issues do turn up in kids' and teen fiction, they appear less so in 'chick lit' novels. Maybe it's because certain kinds of illness instantly mark out a book as 'too serious to be chick lit'? I'm also surprised that chronic conditions specific to women, like endometriosis, don't turn up more often, but again, it's a wide genre and there may in fact be plenty of books out there dealing with various conditions! Any thoughts?

2. A shorter query: anyone know of any academic/critical works which focus on The Babysitters Club series? There's a book called 'Sisters, Schoolgirls and Sleuths' which looks at girls' series fiction but in a broad way – am just curious.

3. What's your favourite fairytale adaptation? (Okay, mostly I just love fairytales. But they seem to be more fun to twist and warp than simply tell.)
