The book details overlay is currently somewhat chaotic, and furthermore, I don't think it's very mobile-friendly.

Doing some analysis, I think we're doing four different things on that overlay:

1. Displaying basic info about the book, that is, cover, title, authors, publisher.
2. Displaying detailed info about the book. This is basically all the other metadata.
3. The series model. This allows the reader to switch to the next comic in the series quickly.
4. Feedback. This is the tagging/commenting/rating, and also things like 'delete book' and I think in the future we might want to try increasing the feedback loop by showing the website of the book, an action for leaving a comment/review using knewstuff, or reminding the reader this author takes donations.

Below is some sketches of my own, with the red being the current state, and the blue suggesting we always show 1. and have 2, 3, and 4 in tabs or something.

Another thing we could consider is whether or not this is too much functionality that is being put into a single overlay. On the flip side however, both 3 and 4 need to be shown at the end of the book, so I am unsure what is wisest.
