While getting back into the swing of things, I found this useful list from Reading Group Guides, the site for book groups: the books whose guides were most requested by book groups in 2016. I've reproduced the "new favorites" half of the list below.
Behold the Goldilocks zone - these books are not too old (leaving you nobody to discuss the book with) and not too new (does anyone enjoy waiting lists? Or not being able to renew a 500 page book?). I have linked to the library eBook versions, many of which you can start reading right now using the Overdrive app. See also: library bookshelves.
