Before admitting to not reading the book, follow these steps. After all, what they don’t know won’t hurt them.
How to pretend you've read a book
Familiarise yourself with the story
Depending on the book, websites like SparkNotes, CliffsNotes and Shmoop all have summaries available for free.
Develop an opinion
This is where Goodreads comes in handy. There are hundreds of reviews published online from people who love to express their opinion. Pick one point, and stick with it. Most importantly, don’t overdo it.
Read a couple of pages
In order to pull this off, you’re going to have to actually read a couple of pages. The beginning, obviously, and flip to the end to find out what happens. If time is on your side, skim through the book to find the information you’re interested in.
Google the author
Google interviews with the author for interesting information and casually work your findings into the conversation.
Refer to other books
Listen to what your fellow club members are saying and see if you can link it back to something you've actually read.
Get in first, share your opinion and hand over the reigns. The longer you wait to contribute, the more pressure there will be to say something original.
