Thanks for the comments! I'm probably just going to leave in the nominations for a series and for a single novel from that series for now, and then if they both pass onto the short list I'll combine them there - there might be some cases where one book is way more popular than the series as a whole.

Re: Kairos, I thought about that, but someone specifically nominated "Kairos" - to me "A Wrinkle in Time series" means the four or five books that feature the Murrys, and Kairos includes the next generation books about Poly and Adam and etc. Other people may read those series names differently, though, I don't know - it's probably going to be confusing to some people either way.

I plan to add a space for "includes" in the spreadsheet and on the poll, though, which might be helpful in those cases!
