Mine's far simpler
- import books in Calibre where they get the "Alf treatment"
- a quick tidy up: cover/medatada/insert jacket into books
- send books to Kindle(s)
- use the collections plug-in to automatically organise my stuff for me on the Kindle(s)
and that's it really (and yeah, 2 backups too

). If a book is really badly formatted, I delete it and ask for a refund, I don't really want to spend time fixing stuff (plus I'd need to learn how anyway...) If the publisher can't be bothered to make sure that the formatting is reasonable in the first place, then I can't be bothered to read it.
