Madonna's new book for children, titled Big-Sister Blues, will be released on May 29th 2008.

Short description:
Tired of being “the nice one,” who is always taken for granted, Binah is ready to try being something— or someone— new. But how will the new and maybe-not-so-improved Binah fit in with the English Roses? And with a certain someone—her latest crush, Ben— who might have liked the old Binah a little bit more than he’d let on? Can her friends prove just how wonderful the real Binah is before “the nice one” is gone… for good?
