Jespah -- You may still be able to look in and participate. In the book club I was in for many years, after some frustrating attempts at getting everybody to read the book, we insisted that anyone who attended must (at least) read the front and back covers of the book... and the Jane Chord. The Jane Chord was named for some long forgotten wife of a book critic who said that much could be learned by putting the first and last words of a book together.
Here are some sample Jane Chords:
Walden -- In star.
Pinnochio -- There boy.
Robinson Crusoe -- I peace.
Farewell to Arms -- In rain.
The Two Towers -- Aragorn enemy.
With that under your belt, you can manage at least part of any discussion!
