Something i do:

1. Find 10-20 friends

2. Go on holiday for a week in a cottage in the middle of nowhere with terrible internet speed

3. Bring a dozen books each and put them in a huge pile in the middle of one room

4. Eat a lovely big meal together in the evening

5. Mercilessly shame anyone who is doing anything other than reading a book, cooking, or performing essential biological functions before dinner time

You don't all read the same book, but there will be plenty of overlap, and it usually works out that there are a few books that many people have read.
