Thoughtlessly changing the names of minor characters makes me gnash, grind, and grimace. I remember that the side-kick's wife's name is Heloise, why can't the author? When J.T. Ellison visited our library after her first book was published I begged her not to do this. She shared that she had binders for major and minor characters, recurring or not, so she won't make that mistake. More authors should follow her lead.
I can remember that the protagonist is an alcoholic and don't need to be reminded in every chapter (The Strain).
Looking for eBooks... NetGalley is a good source. Of course I have to plug public libraries. We have a large eBook collection. I don't know that status of collections outside the USA, but it's worth investigating.
