I suppose that you can read this story without having read the previous, but you won't understand a lot of the references in it, particularly the people involved. It doesn't give any reminders of who they are or what happened previously; it expects that you know. Reading them back to back is best. 
 I think that I have figured out my dislike of the Dick & Shane books - it's that they don't fit into book format well - they're much better in the original blog entry format than as a 'book'. The diary-like format is different, but it's also distracting, particularly for the back-and-forth when some stories are told after the fact. I understand that it makes more sense to do it that way from a realism standpoint, since this is set as an autobiographic work, but because it's so episodic, I don't get sucked into it all the way through - I stop when that piece of the story stops. As a blog that you go back to on occasion, this works really well. As a book, it doesn't (at least not for me). 
 As a book, I keep wishing that it was told in a more typical 1st person fashion all the way through instead of diary-like for the most part with shorter normal stories interspersed. There's not a compelling reason to continue reading the book right that moment, and I know that in the end, there won't have been any point to reading it other than for the "day-in-the-life" stories, which are good, but there's no point - that is other than to know what it would be like, to some degree, to live a 24/7 submissive lifestyle. So, I put it down regularly. 
 I like the characters and story so much that I wish I didn't feel like I could put it down so easily. Even so, it might like it more if it was strictly diary format and didn't take the random breaks for 'story-telling' - I'd rather the stories be told as part of the diary format instead of as separate asides. But the real problem is that there's no true end, and hardly even a lesson learned. (Gillibran is a stubbon sod. He'll tell you so himself.) 
 The issue of how the story is told aside, I really like the stories, the characters, and the mannerisms that come through in the writing, like the "(sorry, Miss)" and the "(Lie detector says NO)" and the "I hate f**king XXXX, not that I ever have, f**ked one I mean" - those always make me smile. Some parts of the story, I felt so bad for Gilli (even if he did bring it on himself) that it even got a few tears. 
 And, Oh My Lord, the figging episode is one of the most hilarious things I have ever read in my life! I sprang many tears of laughter and couldn't breathe properly for quite some time. 
 So, even as anti-climactic as it was, 4 stars.
