Goodreads Book Lists

I have absolutely no earthly clue how a book rises up the ranks of a Goodreads list, but when I checked out a list for books set in Ireland (I've been enjoying contemporary rom-coms set here), I was excited to see that not only was A Time Apart: Book One of the Macauley Vampire Series (which Goodreads still insists labeling as MacAuley) on the list, but it had broken the top 100 ... at #99. Still, wh-hoo!

(Edited to add: Well, not sure why they're all showing up as #99 in this screenshot. You'll just have just have to take my word for it.)
