My library has a 163 paper copies and 10 electronic copies of
The Fault in Our Stars. I'm pretty sure anyone with access to a library can survive this one without a purchase. There's only 1.1 million people in my province.
Never Let Me Go interests me. I'm also curious (if any have read it yet) as to how science fiction / dystopian it is as opposed to romance. I was looking through GoodReads members' shelving of the book. Romance was way down the list of shelves.
Right now I'm leaning to
Ali and Nino and
The Fault in My Stars as my votes, although I think the two public domain classics would also be fine, although
Jane Eyre being another mid-doorstopper length book might lose my vote if it makes it.
Just my thoughts so far.
