I love this series to bits. :) It's truly delightful and I always find myself grinning at various points through the books, just enjoying the pure fun of the narrative.
Not only are the main characters wonderful and flawed and special and adorable, but the secondary and even the tertiary ones are too. Except the baddies. They're just deliciously bad. Unless sometimes they turn out to be good.
I bought the boxed ebook set, but I'm parcelling out the individual volumes so that I don't finish them in one fell swoop. :)
So there you go. Loved it!!
